Title: Radar jamming system used crossed polarisation response to detected signals
Inventor: ANDRE CHARLES VICTOR FLORIMOND
IPC: G01S7/02
Filed: 1983-09-20
Abstract: The radar jamming system operates in crossed polarisation, and comprises a polarimeter (30) whose two inputs (31,32) are connected to two aerials (10,20). One of the outputs (R) of the polarimeter is connected to a matched absorbent load (37), whilst the other output (E) is connected to a noise emitter (40) operating with the time and frequency characteristics of the received radar signal. The aerial output signals (10,20) are tapped off to lead to a polarisation mono-pulse analyser (50) which determines the difference in phase angle between the signals received on the two aerials, and their amplitude, for each incident radar pulse. Using the received signal as a reference, it is thus possible to excite the polarimeter and create the required polarisation for the noise.
