由于目标在高频段电磁散射的测量比较困难，利用电磁波与声波的相似性，我们提出通过测 量刚性物体在水中的声散射强度，来模拟目标的电磁散射。本文从理论上分析了应用超声模拟目标 电磁散射的可行性，并且进行了实验研究。 Due to the difficulty in measuring the electromagnetic scattering in the high frequency range and using the similarity between the electromagnetic wave and the acoustic wave, we propose to simulate the target electromagnetic scattering by measuring the acoustic scattering intensity of the rigid object in the water. In this paper, the feasibility of simulating target electromagnetic scattering by using ultrasound is analyzed theoretically and experimentally studied.
