一种基于卡尔曼滤波的机车测速雷达算法

复杂多变的机车运行环境、前端天线发射的波束过宽等因素，使通过测速雷达得到的机车速度的初始精度不高。以往关于此类问题的分析大多只是针对理论数据，在提高精度的同时会造成速度时问上的滞后。本文提出了一种基于自适应卡尔曼滤波的方法来提高雷达的测速精度，并且结合理论数据和某机车测速雷达在实验中得到的实际数据对算法的合理性进行了验证。

An Algorithm Based on Kalman Filter for Locomotive Speed Radar

Initial speed measurement accuracy of locomotive speed radar is not high enough because of complex and changing environment and limitation of much wide beam transmitted by antenna front end.Most studies on the issue are merely based on theoretical data;moreover the improvement of accuracy would cause time lag.A method based-on adaptive Kalman filter technique is put forward to improve the accuracy of speed measurement;validity of the algorithm is verified by combining of theoretical data and actual data obt...
