Abstract
The bubble backscattering intensity between 140 and 160 degree is achieved utilizing bistatic method, and the bubble scattering signal is detected, analyzed and processed. The photo multiplier tube is used to detect the weak signal. Threshold detection distinguishes between the bubble backscattering and water backscattering. Bubble scattering pulses are stationary random signals and have statistic properties. So the sample average for an enough long time may be as the scattering intensity at a certain angle. Experimental results have the same trend as the theoretical results. The experimental research on the bubble backscattering properties is importance to the ocean sensing and wake homing.
