Abstract
A type of transmitter, that transmits an unexpanded continuous unmodulated signal following a predetermined number of transmission pulses, is disclosed for the regulation of a multichannel pulse compression system. At least two compression channels are available which are inserted between a microwave receiver stage and a demodulator. A respective monitoring signal is extracted from the output of each compression channel and these monitoring signals are compared in a control circuit in order to obtain a phase difference signal and an amplitude difference signal. A respective control signal is derived from each difference signal in order to regulate a phase shifter and an attenuation circuit, which are provided in at least one of the compression channels, in such a manner that the phase difference signal and the amplitude difference signal are compensated towards zero.
