多舰协同侦察的无源测向时差定位方法

Passive DF/ TDOA location based on multi-platform cooperative reconnaissance

提出改进型的无源测向时差定位方法.在测向定位基础上增加了目标到达舰载侦察雷达的时差信息,两舰之间通过测向交叉和时差计算实现对目标的定位,通过两两配对可以获得多组目标位置的测量结果.对这些结果进行简化加权最小二乘(SWLS)点估计,从而获得一个比较理想的定位结果.仿真结果表明定位结果比较理想.

The DF/ TDOA location method was proposed,which increased the TDOA information between shipboard radar surveillance based on the finding location of the target,and the fleet could get groups of target location measurement results by direction finding and TDOA from each two warship group,and then more suitable location results with SWLS point estimate can be obtained.Simulation results show that the location results are comparatively ideal.
