High-order central moment based Detection for Moving Target by Forward Scattering

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

The scattering strength of a target in the forward direction is generally higher than that in other directions. Using the forward scattering, detection of the target may be more easily. However, there is a challenge that when the bistatic angle of the bistatic sonar close to π, the intense direct blast covers the forward scattering wave and it is difficult to separate each other because of the same arriving time, arriving angle and the frequency. For this situation, this paper combines fractional Fourier transform (FrFT) and the high-order central moment between multi frame signals to extract the aberration caused by forward scattering for moving target detection. The computer simulation results show that the direct blast can be suppressed effectively in the stable environment and the aberration caused by forward scattering is more than 20dB.
