摘要

针对传统速率陀螺平台在小型雷达导引头上应用的局限性,分析了捷联式天线平台系统特点。基于多级坐标变换,对捷联式天线平台角速度稳定算法进行了研究,且采用角度卡尔曼滤波和多普勒跟踪回路的信息估算出目标视线角速度。仿真结果表明,多级坐标变换算法能有效保持天线平台捷联稳定,采用卡尔曼滤波和多普勒跟踪回路的信息估算目标视线角速度精度高、计算量小。

Abstract

The system of strapdown antenna platform was analyzed to solve the deficiency of conventional rate gyroscope platform for a small radar seeker. Based on multi-level coordinate transformation, angle rate stabilization algorithm of strapdown antenna platform was studied. Line-of-sight (LOS) rate was estimated with the information of angle Kalman filter and Doppler tracking loop. The simulation results show that multi-level coordinate transformation algorithm keeps stabilization of antenna platform effectively, and the LOS rate estimated with the information of Kalman filter and Doppler tracking loop is more accurate and needs less calculation.

Key words： antenna platform; multi-level coordinate transformation; Kalman filter; LOS rate
