摘要：通过分析无线电近感探测器的信号收发过程,考虑了探测器的工作原理,建立了基带等效收发信号间的基带等效模型,兼顾了无线电信号实际传播的过程及多径衰落,实现了无线电近感探测器基带等效回波的基带等效仿真。利用该方法可实现多种探测器的回波仿真,并可仿真目标与探测器交会时的多普勒频率信号,具有计算量小、实现简单的优点。同时,通过构建无线电近感探测器的工作场景模型验证了该方法有效性,仿真结果表明用该方法仿真得到的时间波形其信号特性与强度均可反映目标与探测器交会的过程及其多普勒频率信息。
The base-band equivalent model between the transmitted signal and its corresponding received signals was established in this paper by analyzing the transceiver of radio proximity detector. Thus, with considering the multiple path loss of received signal, it could be used as one general echo simulation model for proximity detectors, and their different frequency signals could be simulated by this based-band approach. The echo signal obtained by this method could indicate the meeting process of targets and detectors, and its various version waveform for various detecting systems with various Doppler frequency varieties could also be simulated. Furthermore, it has the strong-points of low computation complexity and simple implementation. Finally, the proposed base-band echo simulation method was tested in one radio proximity detector working scenario. The numerical results show that the simulated time signal could reflect the meeting process of bomb targets with relative movements.
