Water based borders are the most difficult area to guard. The broadness of sea boundaries makes them hard to monitor particularly with high numbers of all ships and cargos passing through. Maritime Security is, as a result of this, a complicated process.

Governments wanting to implement effective maritime security should consider state of the art diver detection systems.

Diver detection sonar systems are acoustic location and sonar systems deployed underwater to help detect submerged swimmer delivery vehicles (SDVs) and divers. The main goal of diver detection is to provide classification information, tracking, and detection of underwater threats.

Below are some examples of Diver Detection Systems that can help tighten maritime security:

PULSAR-XS Military Spec Diver Detection System

This type of diver detection system is designed to counter sabotage threat and terrorism attacks on oil platforms, commercial ports, and naval bases among others. Some of the tasks the system can perform include:

• Display of processed detection and classification echoes together or unusual to acoustic "raw" data
• Depth classification of detected targets
• Detection of swimmers, divers, and swimmer delivery vehicles (SDV) in manual and automatic modes
• Automatic target tracking
• Determination of target data like range, bearing, depth, speed, course, length, level and aspect angle

Underwater Pipeline Protection Systems

The underwater knobs of the diver detection system can cover up to 360 degrees while the horizontal coverage the phased array sonar is 98 degrees. Divers can be detected in a radius of 700 m around the DDS Node and all hardware parts are above the waterline in a container.

Maritime security covers both above and underwater borders making it hard to monitor all areas. This is the reason why advance technology equipments are important in order to ensure sea borders are well guarded.
