A system for signal processing using matched filtering after a time compression is provided wherein several signal (S1 ,..S n) are simultaneously processed through a multichannel system. Each signal is successively frequency translated, transformed into splitted complex signal components, further sampled, multiplexed and then quantized. Apparatus is provided for time-compression and a multiplex transmission of the said quantized signal components which are then reconverted, in a transfer unit, into an analog signal translated in the frequency band of a matched filter. Each of the functional units being controlled in accordance with the rythms (H0 , ... Hn) dictated by signals of a control source. The matched filter produces a mutual correlation function between the filter input signal and a time-compressed replica of the transmitted signal waveform at the said filter output. An output unit thereafter produces the processed signal. The system can be utilized to effect matched filtering of signals coming from panoramic sonar equipment with multiple preformed channels. |
