摘　　要：Dear editor,Array antennas, which are able to adaptively gen-erate the mainlobe in the target direction andnotches in the jamming directions, are usually em-ployed by modern radars [1-3]. A notch is adap-tively placed in the mainlobe direction when main-lobe jamming （MLJ） exists, which changes theshape of the mainlobe and decreases the antennagain on the target echo. Hence, in this scenario, itmakes detecting the target or estimating its direc-tion more difficult, and the problem becomes moreserious when MLJ is closer to the target.Dear editor,Array antennas, which are able to adaptively gen-erate the mainlobe in the target direction andnotches in the jamming directions, are usually em-ployed by modern radars [1-3].
