摘　　要：在机载雷达时空二维信号处理中，通常有三种处理结构：空时级联、时空级联和空时联合域结构。尽管联合域最优处理在实际中不大可能应用，但它有极为重要的理论价值，人们已将其有用概念和方法应用于空时级联或时空级联结构中，这时“级联”一词的含意已不再是“空、时频率响应之积”，因而它们的性能将大大提高。本文对比分析了空时结构中几种自适应算法的性能，并讨论了其实际应用的可能性。There are three available configurations in space-time processing for airborne ra-dars:the cascasded space-time,the cascaded time-space,and the joint-domain Although the reali-zation of the joint-domain processing is very difficult,the idea is very useful to improve the perform-ance of cascade schemes.In this paper,we compare the performances of several adaptive two-dimensional processors for airborne radar with cascade space-time configuration,and discuss the possibility of their applications in practice.
