摘要
为高效实现雷达通信一体化,提出了一种基于导频的正交频分复用(OFDM)雷达通信一体化波形设计方法。该方法充分利用通信系统中已有的导频信号,将导频与相位编码信号结合,实现雷达探测功能,且对通信速率等通信性能的影响较小。同时,为进一步增强雷达信号的抗干扰能力,引入混沌序列作为导频的相位编码序列。仿真结果表明,设计的一体化信号的模糊函数图呈优良的图钉形状,具有较高的距离-速度分辨率,同时,整体系统具有较高的通信速率与较低的通信误码率。
In order to efficiently realize the integration of radar and communication,a pilot-based orthogonal frequency division multiplexing(OFDM)radar and communication integrated waveform design method was proposed.The method combined the pilot signal with the phase-encoded signal to realize the radar detection function which had little impact on the communication performance such as communication rate.Meanwhile,in order to further enhance the anti-jamming capability of the radar signal,chaotic sequences were introduced as phase encoding sequences to use on pilot.The simulation results show that the fuzzy graph of the designed integrated signal has an excellent pushpin shape and has high range and velocity resolution.At the same time,the overall system has high communication rate and low communication bit error rate.
