a quiet zone generation technique is proposed for interference mitigation for a receive antenna by injecting the very interference signals via iterative processing , generating quiet zones dynamically for receive antennas . the receive antenna may feature multiple receiving apertures distributed over a finite area . optimization loops consist of four cascaded functional blocks ; a pick - up array to obtain the interference signals , element weighting and / or repositioning processors , an auxiliary transmit array with optimized element positions , a diagnostic network with strategically located probes , and an optimization processor with cost minimization algorithms . to minimize interferences between transmit and receiving apertures in limited space of an antenna farm for communications and / or radar applications are very tough problems . however , solutions for co - site interference mitigation may not be generic ones but more specific to geometries of antenna farms , tx apertures and rx antenna locations , and beam positions of the tx beams .
