ABSTRACT:
1. A side lobe suppression device for use in a directional receiver system omprising
First means for receiving first RF signals and converting them to first IF signals;
Second means for receiving second RF signals and converting them to second IF signals;
First delay means connected to the second receiving means for delaying the second IF signals a predetermined time;
Third means operatively connected to said first means and said first delay means for time sharing said first and second IF signals;
Fourth means operatively connected to said third means for demodulating said first and second time-shared IF signals; and
Fifth means operatively connected to said fourth means for comparing one of said first and second demodulated signals with the other, said fifth means including means for inverting the demodulated signals carrying the same information as said delayed IF signals, and a second delaying means for delaying the other demodulated signals a predetermined amount.
