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。

In some air-ground combined bistatic radar systems,the space positioning error of air-borne emitter has great influence on target location.Aiming at position errors of GPS and disturb-ance of flow,two important sources which cause positioning error of airborne emitter,a data pro-cessing 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 filte-ring.This scheme has effectively decreased positioning error of airborne emitter and is of great im-portance for the study of bistatic radar.
