Abstract: Fracture is a common underground structure phenomenon，which can provide space and passage for the storage and migration of oil and gas． Borehole radar is a fast and high-resolution geophysical detection method，which has been widely used in engineering，exploration and other fields． This paper mainly uses theoretical

analysis and numerical simulation to study the variation law of the characteristics of the received borehole radar signal with the variation of fracture width． The Ｒicker wavelet is used as the pulse signal of the borehole radar．The results show that the amplitude of the signal received by the borehole radar first increases，then decreases，

and finally tends to be a stable value with the increase of fracture width． The results have guiding significance for the detection of underground fractures and the estimation of fracture width by borehole radar．

Keywords: borehole radar fracture width amplitude numerical simulation
