摘要
在空间和功耗严格受限的平台下,采用基于OFDM的一体化技术来实现功率共享、通信速率高、探测和通信可同时进行的雷达通信系统。对比分析了2种基于OFDM的一体化信号的雷达信号处理方式。对基于OFDM的一体化信号的探测性能进行了仿真论证,重点分析了调制符号对于OFDM信号探测性能的影响。在实现探测功能的前提下,分析了信号的一体化对通信性能的影响。改进的OFDM信号能够实现高速通信和雷达探测功能。
At the platform with limited space and power,the radar communication system can be realized by using the integrated technology based on OFDM,and the system has such characteristics as power sharing,high communication rate as well as synchronized detection and communication.This paper compares and analyzes two radar signal processing modes of integrated signal based OFDM.The detection performance of integrated signal based on OFDM is simulated, and the influence of modulation symbols on radar detection performance is analyzed in depth.Based on implementation of detection function, this paper analyzes the influence of signal integration on communication performance. An improved OFDM signal can implement such functions as high-speed communication and radar detection.
