摘　　要：利用空中机动平台搭载光电吊舱对目标进行探测,已得到初步应用.光电吊舱可测量目标相对于平台的方位角、俯仰角,辅以平台GPS位置信息,从而实现对目标的无源定位.传统的定位方法精度不高、收敛速度慢,而且易受测量噪声的干扰.在分析传统三角几何定位方法误差的基础上,提出一种基于最小二乘的目标定位方法,能够有效抑制测量噪声带来的累积误差,并且可以提高定位精度和收敛速度,有望为工程应用提供一种新的实用的目标无源定位方法.仿真结果和实际试验均验证了方法的有效性.It has been applied to passive location field to detect targets using photoelectric payload car- ried by the aerial mobile platform. Photoelectric payload could measure the orientation angle and pitch angle of target relative to platform. With the addition of GPS data of platform, it is possible to locate the target. The existed method has a low precision, slow convergence and is easily disturbed by meas- urement noises. Based on the positioning error analysis of existed triangular method, a new method u- sing the least square estimation to locate target is presented. The new method is able to restrain piled error of measurement noises and improve location precision and convergence performance. What is more, it could be regarded as a new practical passive location method in engineering. Both the simula- tion and the test of experiment data are given to prove the validity of the method further.
