Man Portable Radar
Warning Receiver
Introduction
The unit is designed for Radar Warning Receiver (RWR) applications where small size and low power
consumption are of prime importance, with filtering, amplification, detection and frequency
measurement being combined into one multi-function unit.
Figure 2 shows a block diagram of the RWR and its three integral RF modules. Two amplitude
measurement channels allow direction finding by amplitude comparison between adjacent antennas.
One of these channels is also used in standby mode for detecting the presence of signals by polling
round the antennas. A two-tier discriminator, fed from one of the amplitude channels via an SPDT
switch, performs frequency measurement. Frequency resolution is nominally 160 MHz over an 8 to 18
GHz band.
