摘要

随着更便宜的射频集成电路器件的出现，现在基于外差架构构建便携式阶跃频率探地雷达已经变得可行。这些克服了在纯差系统中遇到的问题，以及确实存在的性能限制因素，能够更有效地控制。本文介绍了一种基于外差结构的50- 800mhz阶跃频率连续波探地雷达的设计。讨论了外差接收机的结构优势，步进频率合成器和收发器的实现，并给出了系统的性能预测。

A 50-800 MHz stepped frequency continuous wave ground penetrating radar

With the advent of cheaper, RF integrated circuit devices, it has now becoming feasible to build portable stepped frequency, ground penetrating radars based on heterodyne architectures. These overcome the problems encountered in the homodyne systems, and the performance limiting factors that do exist, are able to be more effectively controlled. This paper presents the design of a 50-800 MHz stepped frequency continuous wave ground penetrating radar based on a heterodyne architecture. It discusses architectural benefits of heterodyne receivers, the implementation of the stepped frequency synthesizers and transceiver and presents performance predictions for the system.
