ABSTRACT:
The present invention relates to a band compression device which make it possible to match a system furnishing signals of spectral width B, to a system having a pass-band b smaller than B. It comprises successively and serially, a variable threshold gating device, an amplifier and a low-pass filter. Control means, connected to the output of the compression device, for controlling the threshold gating device, and permits a constant false alarm ratio in a radar application.
