Abstract

PURPOSE:To make the suppression of disturbing signals possible when chirp signal and the disturbing signals are superposed with time by subjecting reception input signals of a radar or the like to frequency analysis, and limiting their amplitude on a frequency axis then subjecting the same to pulse compression. CONSTITUTION:An input signal is converted to an intermediate frequency band by a mixer 11, and is made into a Fourier transform waveform by a dispersion type delay line 12, whereby narrow band disturbing signal components are made into large amplitude pulses of sharp peaks and a chirp component S is made into a low amplitude square wave of wide pulse width. The converted waveform is processed with a wide band amplifier 13 and an amplitude limiting circuit 14, and the component J is considerably limited of power. Only the narrow band disturbing signal is suppressed by a compressor 15 forming a matched filter corresponding to the Fourier transformation of the component S in spite of the case in which the component J is superposed with the component S without separation with time, and the chirp signal is easily detected without receiving the influence of said signal.
