摘　　要：针对多传感器测向定位中方位配对的困难,提出分两步的三维多目标纯测向定位方法。该方法先利用方位信息,粗略估计目标二维位置,并采用方位角误差进行粗略的目标真伪判别,再采用蛙跳式梯度法精确求解目标的三维位置,并利用方位角与俯仰角偏差对目标真伪进行判别。仿真结果表明,该方法能快速地以较高概率、较高精度对多目标进行定位。Aiming at the bearing match problem in multi-sensor passive location system,a two-step method of multi-target passive location for 3D bearing measure system was proposed.The first step was adopting azimuth information to roughly estimate target＇s 2D position,and using azimuth error to judge whether the target was real.The second step was solving 3D position of the target by leap-frog gradient method,and distinguishing the target by the errors of azimuth and pitch angels.Simulation results show that this method can locate multi-target quickly with high probability and high precision.
