近年来,随着各种新型元件器件的出现,促进了雷达技术的发展,具有不同特点和用途的新体制雷达陆续出现。本文主要介绍一种结合发射机噪声抑制技术的高空间分辩力(小于10公分)X 波段毫微秒脉冲雷达,它是作为对流动的淡水薄冰层厚度进行探测的设备。这种雷达工作原理简单,同样可用于地质勘探,以及其它要求高空间分辩力的微波载频时域反射计,目前的性能还在改进中,同时也在探索扩大其应用范围。
In recent years, with the advent of various new types of component devices, the development of radar technology has been promoted, and new systems of radar with different features and uses have appeared one after another. This article focuses on a high spatial resolution (less than 10 cm) X-band nanosecond pulse radar combined with transmitter noise suppression that serves as a device to detect the thickness of flowing freshwater thin ice. The radar works simply and can also be used for geological prospecting and other microwave carrier-frequency time-domain reflectometers that require high spatial resolution, and the current performance is still improving and is also being explored to expand its range of applications.
