摘要： 本文着重介绍全晶体管化X波段地面散射计的设计、结构与性能指标.该散射计采用连续波调频体制,收发天线平行安装.架设高度为8~12m,在方位角0~330°,俯仰角0~85°范围内,能以四种极化状态(HH、VV、VH、HV)测量地面及海面目标的后向散射系数σ0.整个系统由高频部件与控制机箱两部分组成,由多芯电缆将它们连接起来.

Abstract: This article describes design construction and characterization of a transistorized X-band ground-based scatterometer. A FM-CW system is adopted. Two antennas transmitter and receiver are parellally mounted on the top of a crane boom(8 to 12 meters above the ground). The measurement of backscattering coefficients σ0 can be obtained with four states of polarizations (HH, VV, VH and HV) in the range of azimuth angles 0~330° and elevation angles 0~85°. The system consists of RF assembly and a control box, with a multiple-core between them.
