摘　　要：针对高速跳频SDPSK调制信号在非合作状态下的检测需求,提出了一种基于射频直采宽带接收机来实现信号检测的方法。该方法首先完成跳频同步,找到跳频信号每一跳的起始点,然后按跳频周期取出每一跳数据,最后针对每一跳数据结合SDPSK信号的特性进行分析给出检测结果。该方法具有实时性强、检测概率高等特点,同时实现设备具有小型化的特点,降低了设备成本及功耗。In order to meet the detection requirements of high speed frequency-hopping SDPSK modulat-ed signal in non-cooperative state,this paper proposes a signal detection method based on RF direct acquisi-tion broadband receiver.First of all,the synchronization of frequency-hopping is completed,the starting point of each hop of the frequency-hopping signal is found,and then the data of each hop is extracted ac-cording to the frequency-hopping period.Finally,the detection results are analyzed according to the charac-teristics of SDPSK signal.The method has the characteristics of real-time and high detection probability,and the effect of equipment miniaturization,reducing equipment cost and power consumption.
