摘要
分布阵列雷达是一种很有发展前途的新的雷达体制构想。它利用多个小雷达相干联网实现有效地搜索与跟踪目标。本文论述了它的一些突出特点和优点,讨论了空时信号处理与天线方向图的一些问题,最后介绍了利用自适应波束形成获得自相干的方法。尽管实现这种体制的雷达还有不少技术难题,但它肯定能得到迅速的发展。
Distributed array radar is a new concept of radar system with great potentiality.It efficiently accomplishes surveillance and tracking using coherently internetted mini-radars.In this paper some salient features and advantages of DAR are described,and some problems associated with space-time signal processing and antenna pattern are discussed,finally a self-cohering method using beamforming technique is introduced.Although a lot of key technical problems are to be solved,the new system concept will definitely be realized in the near future.
