摘要

本文介绍了低成本调频连续波(FMCW)雷达系统设计与实现工作的进展。在保持先前系统的模块化、灵活性和通用架构的同时,主要在雷达的基带部分进行了一些修改。通过室内测距实验验证了该系统的性能。雷达被调谐到2.308-2.675 GHz工作,以保持产生的啁啾的频率线性。实验结果表明,该系统能够以0.4 m左右的距离分辨率检测25 m以内的目标。

Improved baseband subsystem of the wideband FMCW educational radar
This paper presents the progress made on the previous work of designing and realizing a low-cost frequency-modulated continuous wave (FMCW) radar system. While maintaining the modularity, flexibility, and general architecture of the previous system, some modifications are made mostly in the baseband section of the radar. An indoor ranging experiment is done to show the performance of the modified system. The radar is tuned to operate from 2.308–2.675 GHz to maintain the frequency linearity of the generated chirp. It is shown that the system is capable to detect object up to 25 m with range resolution around 0.4 m.
