A simulation study on geolocation target methods based on a three-sphere model

基于远程激光测距信息,对相同距离下的对地目标的单点定位算法和多点定位算法的仿真结果进行分析研究。对于单点定位算法,提出一种三球模型地理定位方法。在相似条件下,多点地理定位精度明显好于单点地理定位精度。再通过分析不同状态下多点定位的空间误差分析定位特性。

Based on the long-range laser ranging information,this paper studies the simulation results of the single-point positioning algorithm and the multi-point positioning algorithm for the ground targets at the same distance.Firstly,for the single-point positioning algorithm,a three-sphere model geographical location method is proposed.It is found that,under similar conditions,the accuracy of multi-point geolocation is significantly better than that of single-point geolocation.Then,by analyzing the spatial error of multi-point positioning in different states,its positioning characteristics are analyzed.
