ABSTRACT
With the development of radar jamming technique, radar anti-jamming measurement becomes more and more important. Interference includes active interference and passive interference. Active interference is more difficult to overcome. Because the main lobe is so narrow that interference is difficult to come through but easy to come through sidelobe. Lower the antenna side-lobe from a certain degree can repress the source interference, but in general, interference signal is stronger than useful signal and usually drowns the useful signal, causes the difficulty aggrandizement to examine signal. Usually the valid method of dealing with this kind of interference from the side-lobe is Adaptive Sidelobe Cancellation (ASLC) technique. As a kind of space filter technique, ASLC has already been adopted at home and abroad. The key step to use this technique is to compute weight value.
