Single Observer Passive Location and Tracking Arithmetic Using Look-Acceleration and Angle Rate of Changing Information

本文提出了一种基于视在加速度与角速度信息的单站无源定位方法,分析了其定位原理和利用该方法对静止或匀速运动辐射源的即时定位.同时提出了一种适合于这一定位方法的目标跟踪算法———测量空间卡尔曼滤波(MSKF)算法.对即时定位精度与MSKF跟踪算法进行了计算机仿真实验,最后,将该定位方法和MSKF算法应用于某次无源定位外场试验中,结果表明了该定位方法的有效性.

The method of single observer passive location using look-acceleration and angle rate of changing information is put forward. The paper analyse the location fundamental and point out that this method have advantage of single measurement location to static or movement emitter with same speed.At the same time the tracking arithmetic（MSKF） adapting to this location method is put forward. Finally, the computer simulation and outfield test of single measurement location and MSKF tracking arithmetic prove that this method is effective.
