STUDIES ON FILTER ALGORITHMS IN ANGLE TRACKING SYSTEM OF WIND-MEASURING RADARS

本文针对测风雷达角跟踪的实际问题,选择恒定增益卡尔曼滤波器作为跟踪滤波器,并对其性能进行了分析和计算机模拟。结果表明:恒定增益卡尔曼滤波器在跟踪精度,对目标机动的响应能力以及可实现性等指标上都具有较好的特性。

In order to solve the practical problems in angle tracking of wind-measuring radars, this paper analyses and compares the properties cf various kinds of tracking filtering algorithms in engineering application. Then, the steady Kalman filtering algorithm is chosen as the tracking filtering algorithm, and the characteristic of this algorithm is analysed and simulated with computer. The results show that the tracking accuracy, the responsibility to target mobility and the implementation of steady Kalman filter are good.
