ABSTRACT:
A high gain, primary receiving antenna and a single scannable auxiliary lar antenna array are utilized. The auxiliary linear array is coupled to means for forming multiple directive narrow receiving beams simultaneously on the auxiliary array, each of which are scanned over an assigned segment of space to locate and isolate a respective one of a plurality of interfering or jamming signals which are also contained in the signal received by the primary antenna. The interfering signals are cancelled by separately adjusting the phase and amplitude of each one of the interfering signals received and then feeding them to a respective signal subtractor coupled to the output of a receiver connected to the primary antenna.
