摘　　要：首先对多站时差定位技术进行了理论分析,然后根据海战场环境下的作战情景对多站时差定位系统的布站方式及定位精度进行了仿真。最后,结合工程应用中的实际情况,利用干涉仪测向系统的到达角测量结果对Chan算法的模糊解进行了优化,定位精度能够达到预期目标。Firstly,the multi-station time difference of arrival(TDOA)location technology is analyzed theoretically,then the station layout mode and positioning accuracy of the multi-station TDOA location system are simulated according to the operational situation in naval battlefield environment.Finally,combined with the actual situation of engineering application,the fuzzy solution of Chan algorithm is optimized by using the measurement results of the angle of arrival(AOA)of the interferometer direction finding system,and the positioning accuracy can reach the expected goal.
