Title:
SYMMETRICAL MEDIUM SURFACE-BASED TARGET ACOUSTIC SCATTERING STEALTH COVER LAYER AND IMPLEMENTATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/000583
Kind Code:
A1
Abstract:
Disclosed are a symmetrical medium surface-based target acoustic scattering stealth cover layer and an implementation method therefor. The cover layer covers a surface of a target to be hidden, the cover layer being formed by interlacingly splicing a plurality of first medium plates and a plurality of second medium plates; and the acoustic impedance r1 of a first medium and the acoustic impedance r2 of a second medium satisfy the following condition: r1r2 = r2, r being the acoustic impedance of a medium in a space in which the target is located. In the target acoustic scattering stealth cover layer provided in the present invention, there are no special requirements regarding the appearance of a cover layer medium but there are broad requirements for medium parameters; in addition, the cover layer has the advantages of a simple structure and convenient acoustic material selection while not being limited by incident acoustic azimuth and working frequency, and can achieve the acoustic scattering stealth of a target in a far field area.
