| 摘 要： | 频率步进雷达是一种典型的高分辨雷达，它可以通过瞬时窄带合成宽带实现距离向的高分辨的同时降低A／D和其他设备的负担。文章介绍了220GHz频率步进雷达的工作原理和测距的方法，并对不同距离处的角反射器进行探测。实验结果表明，太赫兹雷达对角反射器距离向的探测距离精度可以达到厘米量级；同时，还对太赫兹雷达的探测距离进行了验证，最远探测距离可达35m。

| Abstract: | Stepped-frequency radar is typical high resolution radar, it can synthesize a large bandwidth flexibly with low- ering the burden of A/D sampling and other devices. This paper introduces the working principle of 220 GHz stepped - fre- quency radar and its ranging method, detects the ranges of comer reflector in different distances. The results show that the accuracy of ranging can reach centimeter-sacle and the detection range can be up to 35 m in the experiment. |
