摘要线性调频连续波雷达简称LFMCW 雷达，通过采用连续波频率调制的方式来获得距离和速度的相关参数信息。该雷达结构简单，在工作中发射功率小，分辨率高，没有距离盲区，在军用和民用领域的近距离、高精度测量中具有广泛的运用。
本文以此为背景，以精确快速地测量出点目标的距离和速度为最终目标，研究线基于TMS320C6678平台下性调频连续波雷达的信号处理算法设计。
本文的主要内容如下：

Title    Design of signal processing algorithm for LFMCW  radar based on multi-core DSP                                              
Abstract
Linear frequency modulated continuous wave (LFMCW) radar emits frequency modulated continuous-wave to obtain the information of targets, such as range and velocity. With simple structure, low transmitting power, high resolution and no distance blind area, LFMCW Radar has been widely used in military and civilian fields for close-range and high-precision measurement.
With the goal to measure the range and velocity of a point target quickly and accurately, this thesis design the signal processing algorithm for LFMCW radar based on the platform of multi-core DSP TMS320C6678.
The contents are given as follows:
1 The principle of range and velocity measurement method for LFMCW Radar is demonstrated. The beat frequency echo is processed in both time domain and frequency domain, and then "MTD-frequency domain pairing Law" is employed to eliminate the moving target’s range-velocity coupling problem.
2 The LFMCW radar signal processing procedures are designed and implemented in single-core and multi-core on TMS320C6678, respectively. The software framework and the debugging results are given. The correctness of the signal processing procedure is verified. It has been shown that the speed of signal processing on multi-core is about five times faster than that implemented on single-core.
