Circuit for improving the contrast properties the context of keeping between the main echo reception signal and which, in addition to echo reception signal of a radar system

摘要

P the present invention relates to a device for improving the contrast of a radar, in particular of a pulse compression radar. / p & & p & the device includes an integration circuit 22 connected to a detection circuit 21 of the radar. The output 221 of the circuit 22 is connected to a tube indicator of the radar. The integrator circuit 22 has its control input 27 connected to a circuit of the offset distance of 200 controlled by a coincidence circuit at a distance 25. The coincidence circuit at a distance 25 controls the integration of secondary lobes of the video signal frequency alternating at instants determined for a duration equal to the duration of the central peak of a secondary echo. Application to the detection of an ogive is detached from a fuse body of a ballistic. / p
