近太空双基地雷达定位站址误差影响分析
Influence of Platform Location Error of Near Space Bistatic Radar System Location
摘要
Abstract
The unstable constitution of the receive platform of a near space bistatic radar can cause target location error.This paper presents a mathematic model of target 3D location,calculates GDOP and analyzes the relationship between platform location error and 3D location precision with the method of geometric analysis.The research results indicate that the influence of platform location error on target location accuracy is small,and different coordinate axis errors have different impacts on target location error.In addition,VGDOP,which is part of GDOP,is sensitive to the geometry of target position,while HGDOP is not.关键词
