Highlight Model of Underwater Target Acoustic Scattering in the Bistatic System

<p>A highlight model for the target signal in the bistatic system is proposed based on the calculation results of the acoustic field, which means that the target can be equivalent to several highlights according to certain characteristics of the target when calculating the scattering acoustic field. The parameters of the highlight model were given based on the calculation results. Two sets of experiments on the highlight model of the bistatic system were conducted with a fixed transmitter and a target, one being the receiver rotating around the target, and the other being the target rotating around itself at different receiver angles. The comparison of multi angle pseudo color images through experiments and theoretical simulations shows that the scattering highlight model can describe the scattering characteristics of the target to a certain extent. Only geometric highlights were simulated in this article, and it can be foreseen that bistatic system highlight model of scattering waves can be accurately described with a full understanding of the target.</p> <p>&nbsp;</p>
