## MATLAB的雷达信号仿真系统研究

Title    MATLAB-Based Radar Signal Simulation System
Abstract
Computer simulation of radar system possesses advantages of economy, convenience, and flexibility.Hence,the process of the design and evaluation of radar system needs to rely more on computer simulation.Among the numerous kinds of simulation software, MATLAB simulation platform, with its powerful computing capability and  kits which are suitable for the radar design and simulation, has been widely used by radar designers.
The graduation project is based on the MATLAB development environment, using the GUIDE tool to achieve a radar signal simulation system.The system consists of four sub-simulation software: radar target RCS simulation software, radar range equation simulation software, radar signal waveform analysis simulation software and radar echo component analysis simulation software. The system has a good user interface,and four sub-software can be selected and switched under the demand of users. The function of the system is both rich and complete,and the system can run independently,which is helpful for providing software support for the radar experiment courses in colleges. 源`自*六)维[论*文'网www.lwfree.cn
