摘要
前向散射雷达(FSR)可获得高水平雷达截面积(RCS)的特性使其在反隐身中占据重要地位.利用全球导航卫星系统(GNSS)作为辐射源,具有全天时全天候全地域覆盖的优势,通过部署多个接收节点可构建地面/海上/空中目标监视网络.该文针对基于GNSS的FSR发展现状,从目标检测、目标参数估计、阴影逆合成孔径雷达(SISAR)成像及目标分类识别等方面对关键技术和现存问题进行概述,并从组网探测、多目标定位、布站优化和极化信息获取等方面对基于GNSS的FSR发展趋势提出展望.
Abstract
Forward Scatter Radar(FSR)can obtain high level Radar Cross Section(RCS),so it plays an important role in anti-stealth.The Global Navigation Satellite System(GNSS)has the advantage of all-weather coverage throughout the day as a radiation source and the ground/sea/air target surveillance network can be built by deploying multiple receiving nodes.According to the development status of GNSS-based FSR,the key technologies and the existing problems in target detection,target parameter estimation,Shadow Inverse Synthetic Aperture Radar(SISAR)imaging,and target classification are summarized.What's more,the development trend of GNSS-based FSR is prospected from the aspects of network detection,multi-target location,station optimization and polarization information acquisition.
