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.
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.
