基于卡尔曼滤波的组网雷达系统目标跟踪分析

提出了一种快速卡尔曼滤波跟踪算法,用于组网雷达系统对机动目标的跟踪分析.该算法只需要组网雷达系统给数据处理中心提供每个接收机所测得的准确径向距离,然后根据推广卡尔曼滤波技术迭代估算出目标的位置.对机动目标的仿真结果表明,该算法不但大大减小了传统跟踪算法的运算复杂度而且具有优良的跟踪性能,尤其适用于近距离高速运动目标的准确跟踪.

Kalman Filter Design for Netted Radar System to Track a Maneuvering Target

A fast Kalman filtering algorithm of netted radar system is presented for tracking a maneuvering target. The system's each receiving station only sends the target's exact radial distance to data processing center. With extended Kalman filter's iterative method, this algorithm can accurately calculate the maneuvering target's position. Computer simulation shows the good performance of the fast Kalman filter.
