New Naval Radar Detects Swimmers


Along with the fulfillment of traditional missions of ships and crews worldwide, new missions occur in order to meet new threat scenarios. These are mainly driven by asymmetric characteristics, facing Navies and security forces worldwide with new tasks in changing environments. The new Tactical Radar for Surface Surveillance (TRSS) developed by CASSIDIAN, an X-band radar that has been specifically designed to meet these new conditions, offers the technical capabilities to detect even the smallest objects and to cope with difficult environmental conditions in littoral waters.

Design Characteristics

The TRSS radar has been developed for the detection of very small targets in all surface environments. Due to its high resolution, TRSS is able to detect swimmers, periscopes, and drifting hazardous objects like seamines. For onshore surveillance, TRSS detects asymmetric threats such as slow moving land vehicles. Unlike conventional naval radars, it provides optimal detection capabilities, no matter whether over land or sea. Additionally, TRSS can provide helicopter approach support on naval ships. With these versatile characteristics, TRSS is suited to all sorts of defence, security, and safety missions.
TRSS, as the latest member of CASSIDIAN’s naval radar family, is benefiting from the company’s long-standing expertise in radar development. The core sensor is a development of CASSIDIAN’s latest AESA radar technology. Compared to mechanically scanned radars, the beam pointing has greater flexibility due to its AESA-based technology. High Doppler resolution with one to eight beams in parallel accounts for high update rates, the detection of small objects, and slight object movements. Threats can be detected more quickly and effectively, even under harsh environmental conditions. Additional software elements derived from CASSIDIAN’s TRS-3D and TRS-4D naval radar expertise complete the new solution.
On-board a naval ship, the full functionality of TRSS is ensured by using electronic stabilisation with high-performance, 3D antennas that compensate for the ship's movement. There is no need for heavyweight equipment like mechanically stabilised pedestals or below-deck cabinets that makes the radar deployable aboard smaller ships.
According to CASSIDIAN, the low weight of TRSS gives customers the full flexibility for its installation and configuration. The flexible antenna design supports any ship construction either with a single antenna (with radome) or by a multi-panel configuration. Thanks to a redundant design and low error rate, its life cycle costs will be remarkably low.
With its compact design, flexibility, and technical advantages, the TRSS is a solution for a wide range of applications, including
- Detection of targets close to naval platforms
- Detection of land targets from sea
- Ship-controlled helicopter approach (SCA) support
- Support of mine warfare
- Drone detection and guidance
- Surface gun fire control with splash detection
- Support of search and rescue operations
- Harbour surveillance

TRSS combines many years of expertise in the radar business with state-of-the art technology. The new naval radar is complementary to CASSIDIAN's existing naval radar portfolio, including the TRS-3D surveillance and target acquisition radar CASSIDIAN provides to the US Coast Guard for its National Security Cutters and the TRS-4D radar that is available in rotating and fixed panel configurations. The latter is being supplied to the new Type F125 frigates of the German Navy. TRSS' capabilities have also drawn from  CASSIDIAN's experience in the security radar market. The new radar is therefore best suited to support the protection of ships, crews, and mission teams in all naval and littoral environments.
