数据链系统的航迹关联方法

摘要

A track association method based on weighted least-squares estimation and ant colony algorithm is proposed to solve the complicated track association for multiple platforms and multiple targets in the tactical datalink, and the processing model is set up. Ant colony algorithm is improved to satisfy the real-time datalink. The method can set the parameter according to the battlefield circumstance and the measuring error of platforms. Monte Carlo simulation is performed with the constructed model. Results show that this method is feasible and effective.%针对数据链系统中多平台多目标情形下航迹关联较为复杂的特点,提出一种基于加权最小二乘估计和蚁群算法的航迹关联算法,并建立了多平台多目标航迹关联处理模型.为了使蚁群算法能够满足数据链实时性的要求,对蚁群算法进行了改进.通过设置参数的取值使算法能够适用于不同的战场环境和量测误差.对新提出的航迹关联算法进行了Monte Carlo仿真,结果表明了算法的有效性和可行性.
