【摘要】：为了解决雷达通信一体化系统中的雷达信号与通信信号较难分离的问题,在正交频分复用(OFDM)雷达的基础上,提出了一种基于OFDM脉间随机步进频的雷达通信一体化信号模型,通过频率捷变将数据信息加载到雷达信号上,利用随机的步进频率传输数据,从而使一体化信号能同时实现雷达探测和数据通信功能,避免了信号分离。同时设计了雷达通信一体化方案,在雷达接收端,运用相关法实现一维距离成像;在通信接收端,通过带通滤波器组检测频率点解调数据。仿真实验结果表明,一体化信号能实现分米级的距离高分辨和速率为Mbit/s级的数据通信,能够满足大批量数据传输的要求。
[Abstract]:In order to solve the problem that it is difficult to separate the radar signal from the communication signal in the integrated radar communication system, a radar communication integrated signal model based on OFDM random step frequency is proposed on the basis of orthogonal frequency division multiplexing (orthogonal frequency division multiplexing) (OFDM) radar. The data information is loaded into the radar signal by frequency agility, and the data is transmitted by the random step frequency, so that the integrated signal can realize the functions of radar detection and data communication simultaneously and avoid the separation of the signal. At the same time, the integrated radar communication scheme is designed. In the radar receiver, the correlation method is used to realize the one-dimensional range imaging, and the frequency point demodulation data is detected by the bandpass filter bank in the communication receiver. The simulation results show that the integrated signal can realize the high range resolution at the decimeter level and the data communication at the Mbit/s level, which can meet the requirements of mass data transmission.
