摘要
具有极化测量能力的相控阵雷达是世界强国用于导弹防御、空间监视等战略领域的尖端精密雷达,是军用雷达技术竞争的战略制高点。近年来,在精确制导、微波遥感和气象观测等领域也越来越多地出现了极化相控阵雷达,部分雷达系统已成为行业标杆。该文梳理了极化相控阵雷达在各领域的发展历程和系统研制情况,综述了极化测量误差校正、天线方向图重构、极化方向图综合等关乎极化信息精确获取的核心关键技术的研究现状,最后对极化相控阵雷达技术的发展进行了展望。
Polarimetric phased array radar(PPAR)with polarization measurement capability has been the cutting-edge,high-precision radars applied by world powers in strategic areas such as missile defense and space surveillance.And PPAR is the strategic highland of military radar technology competition.More and more PPARs have been applied in antimissile defense,space surveillance,precise guidance,microwave remote sen-sing,meteorological observation,and other fields over recent years in China.And some systems have become benchmarks in the radar industry.This study briefly reviews the development history and system development of PPAR applied in various fields.Next,the state of the art of several key technologies of the accurate acquisition of polarization information,including the polarimetric bias correction,antenna pattern reconstruction,and polarization pattern synthesis,are summarized.Finally,the future developments of PPAR technology are considered.
