  • Mainlobe canceller with motion compensation for use with radar systems
    Patent number: H792
    Abstract: This invention relates to a mainlobe jamming cancellation system which can e used to allow a radar to detect targets even when relative motion exists between the jammer and the radar platform. In particular, this invention relates to a mainlobe canceller that utilizes a main antenna and one or more widely spaced auxiliary antennas in conjunction with one or more phase locked loops (PLL), to automatically align the jamming signals received by the several antennas. The alignment is necessary to realize a high degree of jammer cancellation.
