Abstract
The invention concerns the radars jamming able to coherent side looking cancellation. From a jamming source (SBR), it is created two channels supplying respectively transmission amplifiers (AE1 and AE2) followed by antennas (AP1 and AP2) operating in different polarizations. The former at least of the two channels is subject to fast time variations with respect to the latter, for example with a line of programmable length (LLP).
