摘要
讨论目标的定位精度通常只关心接收站的几何配置,而忽略定位求解模型的选择;通过对定位模型与定位精度之间依赖关系的深入研究,具体分析较少接收站情况下不同定位求解模型对目标定位误差的影响,给出了时差定位体制下几种不同的定位求解模型,并指出多点定位工程应用中模型选择应注意的问题以及解决这一问题的可行性思路。
Dealing with location precision of target,much attention is put on sensor allocation while location algorithm model is always ignored.Effect of target location error at fewer sensors is analyzed under different location algorithm models through studying relation between location algorithm model and location precision.Several location algorithm models are proposed in time difference of arrival（TDOA） location system,and the main questions which should be noticed and the viable solution is also given at model choice in multilateration（MLAT） project.
