TRS 3405

TRS 3405 is operating in X-Band coastal surface surveillance radar specially intended for the surveillance of maritime traffic in straits, harbour approaches, access channels, and harbours.

The Antenna provides an inverted cosecans squared pattern in elevation down to -25º. The polarisation can be switched from linear to circular.

TRS 3410

TRS 3410 is a mobile version with an antenna on a mast and a single-axle trailer. The radar electronics of the TRS 3405 are located in an externally operated container on the trailer.

This radar was largely replaced by the improved Radar Score
