DIGITAL SONAR for surveillance and detection of small boats.

SAES explains the conclusions and results deal with their participation in the European program CLOSEYE. SAES has developed a system based on sonar technology in order to detect the small boats typically used on illegal activities.


SAES has offered a conference entitle “Design and Operational Tests of a Lineal Sonar performed for the detection of illegal boats in Mediterranean shallow waters” during the IV the 4th National Conference on R&D in Defence and Security. The conference focus on the conclusions that SAES has obtained throught their participation in CLOSEYE, an European program lead to the validation of innovative technologies applicable to the surveillance of the EU Maritime Borders.


The program which is in the final development stage is supported by the 7th European Framework Programme and it has been developed in collaboration with important companies. SAES participation is based on the deployment of a linear antenna passive sonar and digital technology as a way for the detection, tracking and identification of illegal activities as drugs traffic or irregular migration. This issue has capital importance for the European Union, specifically to have tested surveillance solutions to be able to face the upcoming security threats and risks. This fact was one of the chances that allow the SAES solution was included at the program.

Besides the sonar deployment, SAES has face to other technological challenges such as: the automatization of the detection system, the tracking and classification, the satellite communication and the development of an effective system to characterized the boats and the data recording in a classification database. Summarizing, SAES has developed and validated a system fully customized for the surveillance tasks.


Currently SAES is working in two lines: the improvement of the antenna detection features and in a more completed classification database.

SAES shows their Diver Detection System at the Monaco Yacht Show

The DDS-03 is being showcased in the NAVANTIA booth (QP45), at Monaco Yacht Show, from the 28th September to 1st October.


At sea, the threats coming at surface water can be easily detected by radar and visually, but usually there is a gap on underwater security. A diver or a small underwater vehicle can evade the traditional surveillance systems and endanger the superyacht and their guests.




The DDS-03 is an underwater security and safety system specially designed for the detection of divers and other threats as underwater vehicles that can be used for the surveillance and protection of anchored ships and ports.









When DDS-03 detects and tracks a threat, automatically generates an alert indicating its position, distance, trajectory and type of contact, allowing cast a deterrent message to the diver or send a patrol to the area. The automatic detection, classification and tracking functions provides reliable alerts of multiple underwater targets with minimal false alarms.



The DDS systems has different ways of deployment depending on the operational use and zones to be protected. It can be easy deployment ‘over the side’ of a superyatch, manually or using a davit crane, and also can be installed in a harbour piers or in the sea bottom, in order to protect any port or infrastructure.


The system, that accomplished with the most rigorous exigencies since their development initially emerged under military high requirements, has also been designed to be simple and intuitive, in fact no specialist operator is required.


By the DDS-03 Diver Detection Sonar, the yacht owners can feel there are not underwater gaps in security, and also the managers of the most important ports, can offer a total security for the docked yachts.

effects of noise in aquatic life


Resumen del Artículo


The growing human activity in the marine environment is generating an increasing impact on this field in general and on the marine fauna in particular. This activity produces a wide variety of kind of pollutions, some of which, as is the case of  hydrocarbon or plastic spills, have traditionally been treated, but other ones, as underwater energy radiations, has started to receive a generalized attention from the scientific community and the society in general since much more recent dates.


These radiations with potential negative impact on marine fauna, as reflected in the Marine Strategy Framework Directive (MSFD), are not limited to the acoustic influence but other influences as the electric and magnetic ones are also included. On this basis, it becomes necessary to have at our disposal systems than let us to register and analyse these influences to determine their levels, evolution and potential damage on marine fauna.


In this context, this study shows the outcomes of the analysis of the acoustic, electric and magnetic background noise from a set of measurement campaigns that took place in an environment of intense human activity in the Mediterranean Sea. These analyses show very significant increments of these radiations in comparison with the values reported in the international literature.


Additionally, and on the basis of the gained experience, an autonomous integrated system to detect and analyse acoustic, electric and magnetic radiations is presented.

The study is based on the analysis of the multi-influence signature generated by the vessels as a basis to classify them. The dataset for the study has been obtained with the Multi-Influence Range System, MIRS which allows to register and analyze simultaneously magnetic, electric, seismic, acoustic and pressure influences.


The study will be presented next Tuesday (21st of June) at 14.00 horas by Antonio Sánchez, the head of I+D+i of SAES (Sociedad Anónima de Electrónica Submarina) inside the session 3B: Undersea Platforms II – Advanced Submarine Subsystems.


Abstract of Article


In the defence field, the reduction of the vessel’s multi-influence signature, as a mean to reduce their detectability, configures nowadays as a vital importance element to accomplish their missions and even for their own survival.MIRS mide le ruido radiado por buques


During the last times, this interest has also moved towards the civilian vessels field, centred mainly in the reduction of the marine environment pollution due to the different energy radiations generated by vessels. In this context, the study centres on the use of the vessel’s multi-influence signature as a basis to perform firstly their detection and secondly their classification from the results of the analysis of correlation among their set of signatures. It is based on real signals from vessels obtained with the Multi-Influence Measurement System, MIRS.


The use of this technique permits to increase the capability of use of the MIRS system in fields as the Mine Warfare or the protection of harbour environments, acting either as an independent system or integrated with other sensors, such as the AIS system or surveillance cameras, which collaborate together in the classification process. At the same time this technique permits to configure databases of classified contact multi-influence signatures in an automated way.


The MIRS is the system used to measure the emissions of vessels.


The SAES Multi Influence Range System (MIRS) for surface vessels and submarines provides real influence measures (magnetic, electric, pressure, acoustic, and seismic) in a real and controlled scenario, to successfully counter related threats. MIRS is among the best systems in the world in its class and compared to fixed stations. A decisive advantage of the MIRS system is that, due to its portability, low weight, low power consumption and high performance, can obtain all signatures of the ship in different geographical locations.


MIRS is also a tool for testing and calibration of:


•      Systems developed to reduce those influences as degaussing systems, ASG, etc.

•       Systems developed for MCM as the mine sweeping systems.



MIRS has been primarily designed using Commercial Off The Self (COTS) components for maximum reliability at minimum cost.

SAES and the Kazakhstani GIDROPRIBOR have signed a Memorandum of Understanding to supply underwater systems to the Armed Forces of Kazakhstan.

The agreement includes installation, commissioning, testing, maintenance and end-customer support of several systems: diver detection sonar (DDS-03) for protection of ports, naval mines both exercise and combat versions (MINEA series) and underwater measurements systems (MIRS).

By the agreement, signed in Astana (Kazakhstan), while the fourth edition of KADEX Defence Exhibition was being celebrated, the collaboration between these companies has been reinforced. They already signed in 2014 a memorandum of cooperation for joint production and marketing of Diver Detection Sonars (DDS-03).
