  • Power rejection apparatus using a null-constrained subarray for MTI radar applications
    Patent number: 4070675
    Abstract: The present invention involves the use of an adaptive power injection apparatus with an existing antenna having a radiation pattern characterized by a relatively narrow main beam and a plurality of low level sidelobes for the purpose of enhancing the performance of the main antenna in a jamming evironment. The said apparatus consists of an adaptive subarray constrained to maintain a null in the direction of the main beam of the existing antenna. More specifically, the said adaptive array is composed of several individual antennae having relatively wide-beam patterns and combined with the existing antenna through individual IF stages all identical to the IF stage of the existing antenna, individual phase shifters which provide phases necessary for maximum reception from the direction of the main beam of the existing antenna and individual adjustable weights.
