基于离心加速度信息的单站无源测距定位方法

Single Observer Passive Ranging and Location Method Using Radial Acceleration Information

针对只测向(BO)方法具有收敛速度慢、定位误差大等缺点,提出了一种利用角度及其变化率、离心加速度等信息进行单站无源测距定位的新方法。对该方法的单次测距误差进行了分析,经多次测量定位计算机仿真结果表明,该方法比只测角定位方法、角度及其变化率定位方法具有更高的定位精度和更快的收敛速度,并且具有更广的应用范围。

To the defect of Beatings only（BO） method which have long convergence time and large location error, this paper put forward a new single observer passive ranging and location method, which used beatings and its changing rate, radial acceleration information. The ranging error of single measurement was also analyzed. From computer simulation result of multimeasurement passive location, it seems that this method has higher accuracy and shorter convergence time than the location method using bearings only or bearings and its changing rates, and it can be applied in more general situation.
