雷达-通信一体化网络设计

Network Design of Integrated Radar and Communication System

近年来,雷达和通信一体化技术已经引起了越来越多的关注。雷达-通信一体化就是在一个平台上实现雷达和通信的功能,将多部雷达组成网络,从而得到精度更高、评估更全面准确的目标信息。提出一种基于步进变频信号的雷达-通信一体化系统,二进制通信信号通过BPSK调制在步进变频信号中,可在较小影响雷达性能的前提下,实现二进制数据的准确传送,同时对一体化网络的建立方法进行了初步分析。仿真结果表明,该系统具有较好的低误码率,这种一体化网络的建立方法是可行的。

In recent years,the integrated radar and communication system has received more and more attentions.The integrated radar and communication system aims to realize the function of radar and commu-nication on a single platform.By making a network consisting of multiple radars,a preciser and more comprehensive assessment of the target information can be received.In this paper,an integrated radar and com-munication system based on stepped frequency signal is proposed.Binary communication signals are modula-ted into stepped frequency signal through BPSK.As a result,the system can transmit binary data precisely with little influence on the radar performance.Then a preliminary analysis of the method of establishing inte-grated network is made.The simulation results show that the proposed integrated system has lower SER. And it is feasible to establish an integrated network by this way.
