Abstract: Interference wave survey through box - wave is to reveal the features of interference wave based on radar analysis by using azimuth angle or areal weighted array. It also can facilitate selection of field seismic acquisition parameters , so as to improve the signal - noise ratio and resolution of reflectance targets. This paper systematically introduces the principles, field acquisition process and data analyzing methods of box - wave survey. Taking theBiyang depression as an example, the application of interference wave survey through box - wave is studied by u-sing both quantitative and qualitative analytical methods.
