摘要
长期以来 ,海杂波特性研究一直是雷达和微波遥感界普遍关心的问题。本文讨论基于矢量网络分析仪组建的波谱计对海杂波特性所进行的多波段 ( S,C,X,Ku)多极化测量 ,包括测量系统、实验描述和数据处理方法 ,通过数据分析得到不同海态下杂波特性 (散射系数、多普勒谱等 )随频率、极化和入射角 (含小擦地角 )
It is well known that the study of sea clutter characteristics is very important for radar and microwave remote sensing.The multi-band (S,C,X,Ku) and multi-polarization characteristics of sea clutter measured based on the vector metwork analyzer HP8720C are described in this paper.The measureing system,experimental description and methods of data processing are included.The relationship between clutter characteristics (scatter coefficent, doppler spectrum) and frequency,polarization incident angle (including low-grazing angle) are obtained and some typical results are given.
