摘　　要：针对常规警戒雷达数据处理实时性低,无法作为制导雷达接入武器系统问题,提出了一种实时计算的数据处理方法。新方法使用交互多模型方法进行航迹滤波,再结合二阶多项式预测技术获得目标的实时位置。实验证明新方法解决了警戒雷达数据处理实时性低的问题,提高了输出航迹的数据更新率,可以很好的跟踪目标的实时位置。Tracks generated by surveillance radar are of high processing latency and low data updating rate, thus not suitable for guiding missiles in weapon system. The new algorithm stated in this paper employs interactive multiple model algorithm to generate filtered tracks, then uses second order polynomial prediction method to get real-time position of target. Experiments prove that this algorithm can solve the latency problem of surveillance radar, improve data updating rate, and has graceful performance on tracking real-time position of target.
