摘要

针对传统脉冲雷达存在距离盲区，无法实现对近距离目标的探测的问题。针对近距离目标检测的需要，提出了一种基于调频连续波系统的解决方案。采用零中频接收方案，采用收发分体天线，配以调频连续波，可有效实现Om ~ 150m的盲区。本文给出了近程目标检测的原理，重点介绍了在有限资源下用FPGA实现的FMCW雷达的信号处理过程。仿真和现场测试结果验证了系统方案的可行性。

FPGA Based Short-Range Targets Detection System with FMCW Radar

Aiming at the problem that there exists distance blind area for traditional pulsed radar so as to it cannot realize the detection of targets within short range. A solution based on the frequency-modulated continuous wave system is proposed to meet the demand of short-range targets detection. By adopting the zero intermediate frequency receiving scheme, using the transceiver split antennas, and with the frequency modulation continuous wave, the blind area ranging from Om to 150m is effectively achieved. In this paper, the principle of short-range targets detection is given and the signal processing process of FMCW radar implemented by FPGA with limited resources is emphatically introduced. The results of simulation and field test verify the feasibility of our system solution.
