A method and apparatus for use with a multichannel receiver to eliminate signal sidelobes within a received signal time frame is disclosed. The elimination of signal sidelobes within a channelized receiver is accomplished by using an analog preprocessor. The analog preprocessor is capable of producing an amplitude mask based upon the determination of the greatest amplitude and frequency channel in a two-dimensional receiver system or frequency channel and time slot in a three- dimensional receiver system signal. The amplitude mask covers a predefined space in time and frequency equal to or below the peak signal amplitude. A signal in the frequency/time cell space covered by the mask must have a magnitude exceeding the magnitude of the amplitude mask in order for the signal to pass through the analog preprocessor for further processing.
