TRS-4D cleared to sail.
The TRS-4D is an evolution of Cassidian's TRS-3D. It features a rotating aesa (active electronically scanned array aerial, although the F-125 frigates will have four static antennae located on the superstructure to provide 360[degrees] surveillance(because, according to the official, of both the overall topside design of the Type-125 and German Navy antenna redundancy requirements).
Broadcasting in the low C-band at four-to-six megahertz, the TRS-4D has been developed privately by Cassidian. The radar can scan up to 50[degrees] in azimuth when the antenna is stationary, and from 2 to 70[degrees] in elevation. The employment of a mechanically 30 to 60rpm rotating aesa allows the sensor to perform multi-function air and surface surveillance operations over 360[degrees]. Alternatively, the antenna can be kept stationary with the antenna fixed on a defined segment of space.
The radar has an instrumented range of up to 250 kilometres (135 nautical miles) and a minimum coverage of under 100 metres (328 feet). Targets of under 0.01 square metres radar cross section can be detected with the TRS-4D, with around 1,000 targets being tracked simultaneously. The TRS-4D is supplied with a three-channel integrated identification friend or foe antenna, and its electronic counter-counter measure performance is enhanced with very low sidelobes and adaptable transmission power.
