中文摘要：

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。

英文摘要：

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.
