| 摘 要： | 在一些空地结合的双基地雷达系统中,机载辐射源的空间定位误差对目标定位有着重要影响.针对机载辐射源定位误差的重要来源GPS定位误差和空中气流扰动,研究了一种数据处理方案,通过建立GPS定位误差模型,并结合不同载体运动模型,对误差进行卡尔曼滤波处理.该方案有效减小了机载辐射源的定位误差,对双基地雷达研究具有重要意义.

| Abstract: | In some air-ground combined bistatic radar systems,the space positioning error of airborne emitter has great influence on target location.Aiming at position errors of GPS and disturbance of flow,two important sources which cause positioning error of airborne emitter,a data processing scheme is studied in this paper.By building a GPS error model combined with different models of vehicle movement,the error is processed by adopting the method of the Kalman filtering.This scheme has effectively decreased positioning error of airborne emitter and is of great importance for the study of bistatic radar. |
