摘　　要：当空间中存在大带宽、频率快速跳变的辐射信号时,传统侦察接收机无法实现完整接收与准确识别。针对上述问题,提出一种宽带精细化侦察处理方法,实现了宽带实时数据采集与精细化时频分析,获得了多部辐射源信号特征参数的准确分类,并且生成了完整的辐射源态势信息与有效的敌方行为预测结果。实验结果表明,该方法能够实现宽带高速跳频信号的全概率接收及精确解析测量。When there are radiation signals with large bandwidth and rapid frequency hopping in space,traditional reconnaissance receivers cannot achieve complete reception and accurate identification.Aiming at the above problem,a broadband refined reconnaissance processing method is proposed.By this method,the broadband real-time data acquisition and refined time-frequency analysis are realized.Also the characteristic parameters of multiple radiation source signals are accurately classified.In addition,the complete radiation source situation information is generated and effective enemy behavior is predicted.The experimental results show that the method can realize the full probability reception and accurate analytical measurement of broadband high-speed frequency hopping signals,which has engineering realization value.
