摘　　要：针对双发单收目标定位问题构建基于时间差和多普勒频率的联合定位模型,研究多观测值的目标定位解算及联合定位系统误差分析方法。仿真分析基于时间差多普勒频率联合定位过程中观测时间和各参数误差对目标定位的影响。仿真结果表明联合定位方法在较短的观测时间内,能够获得较好的目标位置和速度定位信息。In view of the problem of the double transmitter and single receiver location system,the joint location model based on time difference of arrival and Doppler frequency is established in this paper.The performance analysis methods of location algorithm and performance analysis are given.The location accuracy of the jointing time difference of arrival and Doppler frequency schemes are simulated by different observation time and parameter errors scenarios,the simulation results show that the accuracy of the location algorithm can obtain better target position and velocity positioning accuracy in a short observation time.
