摘要

低速水面目标由于在雷达扫描周期内运动距离较小,受雷达测量精度的限制,导致通过航迹滤波输出的航速误差相对目标航速而言往往较大。针对该问题,分析了距离、方位、俯仰各测量误差对航速精度的影响,提出一种基于两级策略的航速精确解算方法。最后,通过仿真试验对算法进行验证,结果表明该算法能够有效提高航速精度。
        The movement distance of low-speed surface target is small during the radar scan cycle, subject to the measurement accuracy of the radar, the speed error output through the track filter is often large relative to the target speed. For the problem, analyzes the influence of distance、bearing and elevation measurement error on speed accuracy, and proposes a speed accurate calculation method based on two-level strategy. At last, the algorithm is validated by simulation experiment,the results show that the algorithm can effectively improve the speed accuracy.
