基于先验知识的广义旁瓣对消器 STAP
GSC STAP based on a prior knowledge
摘要
Abstract
The computational burden and performance of space-time adaptive processing(STAP)have formed a realistic contradiction.A new STAP approach based on a prior knowledge using the generalized sidelobe canceller(GSC)was pres-ent to solve the above problem.The new approach employed a prior knowledge of the parameters of phased array radar sys-tem and geometry model in order to construct space-time clutter matched vector and matrix.Then space-time multiple-con-straint steering vector was computed to initialize the adaptive weight vector of STAP.The novel STAP avoided the covari-ance matrix inverse in order to obtain fast speed.Finally,the simulated results showed that the method can greatly speed up the convergence with no reduction of performance.关键词
