## Matlab雷达目标回波模拟仿真+文献综述

Abstract
Modern radar systems become more complicated, it is difficult to use simple intuitive analysis method for processing, therefore, radar system simulation increasingly get promotion. Radar system simulation method of economic, flexible and convenient, in the radar research field and engineering technology has been widely used.
This article based on linear FM pulse radar, of radar simulation and processing. This paper mainly work is pided into three parts: linear FM continuous wave radar system and radar simulation with Matlab simulation software is introduced, the echo signal, target echo signal generation process analysis. First, this paper introduces the principle of LFMCW radar system and radar target echo simulation of the principle of wave generated, and then the signal of the software Matlab simulation are introduced and Matlab simulation the echo signal images, finally, introduced the use of FPGA in the images of the data to signal processing and analysis, finally draw target echo of the process. This paper presents A complete sawtooth wave LFM radar system simulation and the treatment process, simulation of the radar echo data after radar signal processing and D/A treatment, and finally form the echo signal.

Keywords：     LFMCW ，   FPGA ，  radar target echo simulation
