摘　　要：有源雷达与电子支援措施(ESM)数据关联是雷达与ESM数据融合的前提。通过测量数据的坐标变换,对ESM数据基于灰色代数曲线模型(GAM)进行平滑,同时对雷达数据采用卡尔曼滤波和预测,实现了雷达与ESM数据的时空对准。最后给出了基于方位差和方位变化率之差的判决函数以及数据关联判定逻辑。The data association of the radar to the electronic support measurement （ESM） is the precondition for the data fusion of the radar and the ESM. By coordinate transformation for the radar and the ESM data, the ESM data are smoothed based on grey algebraical curve model （GAM） and the radar data are processed by Kalman filtering and prediction. Then, the temporal and space alignment of the radar and the ESM data is achieved. Finally, the decision function and the easy data association decision-making logic based on the azimuth difference and the azimuth rate difference are presented.
