多目标测向交叉定位时易产生大量虚假定位点,通过量测与目标之间的约束条件最大限度缩小假设集,再通过计算不同浮标组合下目标的距离相似度来滤除虚假点,获得目标真实航迹。该方法无需先验信息,只需3个测量平台,降低了平台间时间同步和数据互联的复杂度。仿真实验表明,应用该方法可以快速、稳定地完成多目标数据关联,具有良好的工程应用价值。
A large number of false anchor points are easily generated when multi-target direction finding crossover is located. The hypothesis set is minimized by the constraints between the measurement and the target, and the false points are filtered out by calculating the distance similarity of the targets under different buoy combinations to obtain the target Real track. This method does not need a-priori information and only needs 3 measurement platforms, which reduces the complexity of time synchronization and data interconnection between platforms. Simulation results show that the proposed method can quickly and stably accomplish multi-target data association and has good engineering application value.
