The TRS-4D is a multifunctional three-coordinate surveillance medium-range radar with an active digital antenna array (CAR) of the new generation [2] . The radar TRS-4D is designed to detect targets and designate weapons systems to defeat them when solving air defense and anti-aircraft defense missions. It operates in the G-band frequency , detects, tracks and classifies various types of air and sea targets, with particular attention to small, high-speed and low-flying targets and / or maneuvering anti-ship cruise missiles and aircraft, small maneuvering surface targets, and helicopters that are in hover mode. Improved radar resolution characteristics allow detecting targets of reduced visibility, the EPR values of which are less than 0.01 m² [1] .

The TRS-4D multipath radar was developed by Cassidian / EADS , which since January 2014 has been an Airbus Defense and Space division of the diversified concern Airbus Group . The development was carried out at the expense of the company's own funds based on the TRS-3D radar. In January 2013, the radar TRS-4D was chosen by the German Navy to equip F125 frigates of the Baden Wuerttemberg class. [3]
TRS-4D allows ships of class from patrol ships (corvettes) to frigates inclusively to solve a complex of tasks for detecting various types of targets both in the open sea and in the difficult situation of the coastal zone with high density of targets and in the presence of asymmetric threats [4] .
A key element of the CAR technology used in the TRS-4D radar is solid-state transceiver modules (MRP) based on gallium nitride (GaN).

In Europe, Cassidian is a leader in the development and application of this technology [5] [6] , which allowed the company to fully exploit the advantages of multi-path radars with CAR and AFAR in medium-range maritime radars within an affordable solution. MRP work in the mode of reception and transmission with digital synthesis of the radiation pattern .
Two radar options
Two radar variants have been developed - a modification with a rotating antenna (mechanical azimuth scan and electronic azimuth and elevation scanning) and a fixed antenna, represented by four fixed antenna arrays (electronic scanning in azimuth and elevation angle). The version with four fixed antenna arrays has been in production since 2011 to equip the new F125 frigates of the German Navy.
The radar functionality in the version with rotating CAR provides high speed update results of tracking level less than a second, while tracking accuracy is beyond the capabilities of conventional radars with tracking mode in the process of review on search efficiency, tracking start, accuracy and continuity of tracking.
