基于煤层瓦斯超声检测的脉冲压缩技术
摘要
Abstract
for the present conventional ultrasound diagnosis of high frequency ultrasound signal dif icult to get inside seam, low-frequency ultrasound signal detection accuracy is lower, the technique of pulse compression, mainly is the linear frequency modulation pulse compression signal. The technology can effectively improve the signal-to-noise ratio and the precision of the system. This article first to the pulse signal and linear.关键词
