摘要

P device for disposal of fixed echos, more particularly in a radar system, comprising a normal track and a control. / p & & p & the control means comprises at least a logarithmic amplifier and a calculation circuit, constructing the measurement of the average amplitude of the echo signals on a cell azimuth distance, and then on one or several turns of the antenna. This last mean value of the amplitude of the video signals serves to control the gain of the linear amplifier of the normal path of the device. / p & & p & application to the radar, 2002,.... / p
