摘要

对于小卫星编队雷达系统来说

基线是编队构形设计的关键

本文主要从AT-INSAR(Along Track Interferometry Synthetic Aperture Radar

简称AT-INSAR)测速精度方面来分析基线:首先根据小卫星编队空间几何关系

建立了空间基线的模型;接着建立了主星带伴随小卫星编队雷达系统AT-INSAR模型;基于这两个模型

分析了空间基线对于测速精度的影响;最后以"干涉车轮"为例仿真分析了空间基线对于AT-INSAR测速精度的影响

得到了有用的结论.

Abstract

Baseline is the key of formation flying for satellite cluster.Baseline is analyzed from velocity resolution of along-track interferrometry SAR:firstly

based on spatial geometry relation

the model of spatial baseline is established;then

the model of along track interferometry SAR is established;based on the two models

the influence of spatial baseline on velocity resolution is analyzed;finally

take example for "Interferometric Cartwheel"

the influence of spatial baseline on velocity resolution is simulated and calculated

and the results are useful.
