一种多雷达多目标抗系统误差航迹起始方法

An Approach of Multi-Target Track Initiation in Multi-Radar Net with System Bias

提出了一种多雷达多目标抗系统误差航迹起始方法,该方法利用不同雷达对同一目标探测具有较大相似性的特点,对接收到的多部雷达点迹,经初始相关序列提取、相关序列近邻假设整体分配、目标初始状态估计等环节,进行多雷达航迹起始,有助于解决因系统误差估计与数据关联互为前提而无法对目标实施精确跟踪的问题。仿真结果表明,该方法能够对多雷达点迹进行有效互联,提高存在雷达系统误差条件下的航迹起始正确率。

An Approach of Multi-Target Track Initiation in Multi-Radar Net with system bias is developed. According to the characteristic that differ radar would get similar Measure for the same target, this method include three main step ： picking associate point sequence,near neighbor hypothesis whole allocation, estimating of target initiation state. This way can help to solve the question that bias estimation and data association depend on each other. The simulation result indicate that the presented approach can improve the probability of correct track initiation in multi-Radar net with system bias.
