Primary Surveillance

Confident Situational Awareness

The transmitter is a fully modular, fault tolerant solid state amplifier with 8 power modules using the latest Gallium Nitride (GaN) technology. Each power module is designed for 24/7 operation and provides increased reliability with graceful degradation and hot-swap functionality.

The receiver has two channels in order to support simultaneous reception of two frequency bands. Optimum signal-to-noise ratio (SNR) performance is ensured by low noise amplifier(s) located up-mast at the antenna. A very high instantaneous dynamic range of the receiver enables detection of small targets without saturation from large targets/reflections like wind turbines.

After down conversion to intermediate frequency (IF) in the receiver, the signal is sampled with 14 bit at 400 MHz, demodulated, pulse compressed, and moving target indication (MTI) processed. Video processing is performed on both normal radar video and MTI video and includes automatic adaptation to the environment, channel combining, interference filtering, and Doppler processing to suppress stationary targets as well as moving clutter.
