摘要 本文介绍了一种低平台X波段陆基散射计──LS-X4型雷达散射计。小型化的思想,使本散射计具有轻便灵活、适于野外实验操作的特点。高智能的设计,则使整个数据采集与处理完全智能控制完成,十分方便可靠。通过实验证明,LS-X4型散射计十分适于室内及野外机动作业,其稳定可靠的性能,可为各领域微波遥感测量提供服务。 A small-scale,low platform,X-band ground-based Scatterometer LS-X4radar scatterometer is introduced in this paper.Here we describe the design idea and method for realization of small-scale andhigh intelligence transmits.The system transmitts linear frequency-modulated continuous waveform,and ithas long-term stability of high/low temperature.The specification of scatterometer is as follows:Type FM-CW Bandwidth of FM1200MHz Measuring precision of σ ̄0±1dB Total weight of antenna platform≤25kg Height of antenna platform 3.5m Range of height 2─4m System power dissipation(excluding computer)30W Only one person can operate this system, and the rotation of antenna, the ad-iustment of polarization mode,the processing of measure can be controlled by handor program.This high intelligence scatterometer system consists of a microcomputer connec-ted with the antenna platform by a 15 20m cable,a LS-X4 intellegence interfaceboard and systemd diskette.When system running,the current window given by the system program guidethe user to operate easily If necessary,the user can expand the functions as desiredby himself and perform post-processing to the data.If the measuring process mustbe completed outside the door.a portable computer may be equipped.In conclusion,the LS-X4 ground-based scatterometer can be applied in labora-tory or outside the door,and provide service in many fields of microwave remotesensing.
