过去三十年,电扫描相控阵雷达主要用来完成对大量目标的高数据率跟踪。本文阐述了相控阵显露出来的潜力及其在地空导弹系统、弹道导弹防御、舰射弹道导弹预警、弹道导弹试验观测、靶场测量、卫星监视和机载雷达等方面的应用。同时还论及了相控阵尚未得到广泛采用的原因,并对其发展前景作了一些预测。 For the past three decades, electro-scanning phased array radars have mainly been used to accomplish high data rate tracking of a large number of targets. This article describes the potential of phased arrays and their applications in surface-to-air missile systems, ballistic missile defense, shipborne ballistic missile warning, ballistic missile test observations, range measurements, satellite surveillance and airborne radars. At the same time, the reasons why the phased array has not been widely used are also discussed, and some predictions of its development are made.
