摘　　要：针对大带宽条件下传统雷达信号环境模拟实时计算结构实现困难和任意波形发生(AWG)实现方式模拟时间有限的问题,提出了一种基于触发序列的实现方法.通过触发序列的计数,生成信号波形输出的触发脉冲,然后通过后级的幅相矫正,实现超宽带雷达信号环境的有效模拟.最后利用高性能信号处理平台SDR14实现了模拟器的开发.实测结果表明,该模拟器可实现最大带宽600MHz的雷达信号模拟.Considering a few problems that the implementation of analog real-time computationconfiguration of traditional radar signal environment is thorny and the analog time of arbitrary waveformgeneration （AWG） implementation modes is limited in the case of large bandwidth, this paper puts forward animplementation based on triggering sequence. By counting the triggering the sequence, the triggering pulsesoutput by generated signal waveform can be corrected through phase-amplitude in the following stage, thusimplementing the effective analog under the environment of ultra wideband （UWB） radar signals. And finally, byusing SDR14, a high performance signal processing platform, the development of simulator is implemented. Bythe real measured results, it is shown that this simulator can be used for simulation of radar signals with maximumbandwidth 600 MHz.
