Study On The Adaptive Side-Lobe Cancellation Techniquein In Phased Array Radar

In this article, the restraint of active interference from side-lobe of radar antenna with digitalsignal processing technique ?adaptive side-lobe cancellation technique" is discussed. Consideringthe development of phased array radar, some questions: the work principle of adaptive side-lobecancellation, the cancellation effect N assisting channels against R interference sources, therelationship between interfering signal and the power of side-lobe cancellation is analyzedtheoretically. The paper provides the best requirement of side-lobe cancellation and emulates thepositive effects of phase disaccord of the channel. The results will help to consult the designing ofphased array radar with adaptive side-lobe cancellation and to analyze its performance and function.Here, we provided an optimizing design better than the sample system. This design could providethe properties of smaller cubage, compact structure, higher precision and shorter response time.Besides, the adaptive side-lobe cancellation system realized by ADSP2 1062 is introduced.
