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。
In space-time two-dimensional signal processing airborne radar, there are usually three kinds of processing structures: space-time cascade, space-time cascade and space-time joint domain structure. Although the optimal joint domain processing is not likely to be practical in practice, it has extremely important theoretical value. People have already applied their useful concepts and methods to space-time cascades or space-time cascades. In this case, “cascaded” The meaning of the term is no longer “empty, when the frequency response of the product,” and therefore their performance will be greatly enhanced. This paper compares and analyzes the performance of several adaptive algorithms in space-time structure, and discusses the possibility of its application.
