为了解决雷达与通信一体化的应用需要问题,在频率分集阵雷达基础上,提出一种基于随机频偏调制的频率分集阵雷达通信一体化波形。将具有随机性的通信信号调制在频率分集阵雷达的频偏上,并在通信信号间增加随机频率间隔,设计出雷达通信一体化信号模型。通过发射一种脉冲信号同时完成通信数据的传输和雷达目标定位,从而实现雷达通信一体化。仿真结果验证了雷达通信一体化波形在占用较少雷达脉冲资源和满足应用需要的前提下,可以通过有效传输通信信息来提高雷达系统的性能,实现特殊环境下的雷达目标定位。

In order to solve the application needs of radar and communication integration,on the basis of frequency diversity array radar,a frequency diversity array radar communication integration waveform based on random frequency offset modulation is proposed.By modulating random communication signals on frequency deviation of frequency diversity array radar and setting random frequency interval between communication signals,a radar communication integration signal model is designed.By transmitting one kind of pulse signal,the transmission of communication data and the radar target location can be completed simultaneously,so as to realize the integration of radar communication.Simulation results verify that radar communication integration waveform can improve the performance of radar system by effectively transmitting communication information and achieve radar target positioning task under special circumstances under the premise of occupying less radar pulse resources and meeting application needs.
