摘要
为了提高通信速率,又要保持探测能力不受影响,拟采用极窄脉冲的线性调频信号(LFM)作为探测信号,连续相位信号作为通信信号,以相乘的方式结合起来,从而设计出一体化信号的波形,并提出一种解调方案得到通信信号。然后以仿真的形式,给读者阐明其可行性。仿真结果表明,当线性调频信号的脉冲宽度为5 s,频带宽度为200MHz时,一体化信号仍能保持良好的探测能力,是一种对探测能力影响非常小的一体化信号类型。
In order to improve the communication rate and keep the detection ability unaffected,it is proposed to use the LFM signal with very narrow pulse as the detection signal,the continuous phase signal as the communication signal,and combine them in the way of multiplication,so as to design the waveform of the integrated signal,and put forward a demodulation scheme to get the communication signal.Then in the form of simulation,the feasibility of the simulation is explained to the readers.The simulation results show that when the pulse width of LFM signal is 5μs and the frequency band width is 200 MHz,the integrated signal can still maintain a good detection ability,which is a very small impact on the detection ability.
