   Abstract:
   In this paper, the problem of radio frequency interference caused by leak energy from signal source in cross-borehole impulse radar is presented. These interferences reduce the focused image quality. A method based on the frequency difference between signal and clutter is put forward to improve signal-to-noise-ratio and the corresponding infinite impulse response band-pass filter is designed before the delay-and-sum processing. It is proved with field data that the filter improves the image result and makes the signal energy more focused. © 2014 IEEE.
