对 Ｊ Ｅ Ｍ 效应进行数学建模后详细分析了飞机回波谱线特点；利用累量域谐波恢复的 Ｅ Ｓ Ｐ Ｒ Ｉ Ｔ Ｅ 方法，对利用常规低分辨雷达实测某型号飞机动态数据进行处理，得到了 Ｊ Ｅ Ｍ 调制谱线；并从中提取了目标的转速以及旋翼数目等特征量，处理结果证实了所建数学模型的正确性；最后，对两种型号飞机进行识别研究，得到很高的识别概率
After mathematic modeling of JE M effect, the characteristics of aircraft echo line are analyzed in detail. By using E S P R I T E method, which is based on the recovery of the total harmonic wave, the dynamic data of a certain type of aircraft measured by conventional low resolution radar And get the EMF modulation spectrum. The speed of the target and the number of rotors are extracted from the results. The processing results confirm the correctness of the mathematical model. Finally, the recognition of the two types of aircraft is very good. High recognition probability
