雷达阵列信号处理技术的新发展(四)

The Latest Development in Radar Array Signal Processing Techniques

从本期开始,我们将陆续刊登罗景青同志和保铮教授的讲座“雷达阵列信号处理技术的新发展”。讲座共分八讲,主要讲述阵列信号处理技术的发展历史、基本原理及其在现代雷达中的应用情况等,预计在年内登完。保铮教授系学部委员,在百忙中为本刊开设讲座,为此,我们表示衷心的感谢。

In recent years,there has been a great progress in the field of array signal processing. As a primary part of the field,there are quite a few new concepts and methods in radar array signal processing. Some of them have been employed in the practical applications, but most of them are still in developing situation,and they may bring us bright future in the field. This lecture diseusses the main parts of the results in these years in the field of radar array signal processing. The lecture is divided into eight parts. Part one is the introduction, it introduces the development history of radar array signal processing. Part two is about the background knowl- edge of the contents,some linear algebraic theories used in the lecture and the mathematical models in array signal are introduced. Part three is about filtering processing techniques of array signals. The Fourier processing techniques and maximum entropy spectral estimation etc. are included in this part. Part four is about adaptive array signal puocessing techniques. The primary principle and algorithms of the field and the development of modern adaptive arrays are discussed. In part five,we discuss the signal subspace processing techrdques of array signals. Some statistical performance of eigenstrueture approaches are discussed in part six. Part seven is about the maximum likelihood estimation (MLE)of direction of arrival(DOA)for array signal. In part eight, some applications of array signal processing in modern radar system are finally scussed.
