摘要: 针对传统煤矿突水超前探测方法存在探测深度和分辨率无法同时提高的问题，提出了一种采用微波混沌信号作为雷达探测源的方法。该方法通过Colpitts电路产生580 MHz的混沌信号，进而将该混沌信号作为探测源应用于煤矿突水超前探测中，得到与探测距离无关的探测分辨率为5.5 cm，提高了探测精度。

Abstract: In view of problem that traditional method for advanced detection of coal mine water inrush cannot improve detection depth and resolution simultaneously, a method taking microwave chaotic signal as radar detection source was proposed. The method takes 580 MHz chaotic signal generated by Colpitts circuit as detection source, then applies it to advanced detection of coal mine water inrush, so as to get resolution of 5.5 cm unrelated to detection range, which improves detection accuracy.
