Embodiment Construction

[0021] Aiming at the deficiencies of the prior art, the present invention proposes an omnidirectional angle reflector and a verification method for enhancing radar scattering characteristics. By adopting the form of an omnidirectional angle reflector, it solves the problem of greatly improving The problem of the target feature controlling the average RCS of the product has the advantages of light weight, small volume, and small filling space. In order to enhance the target characteristics and control the radar scattering characteristics of the product, the present invention, according to the principle of triangular corner reflectors, combines three right-angled sides of three aluminized polyester films orthogonally to make the incident The electromagnetic wave has three reflections, which greatly increases the RCS average index of the product.

[0022] Due to the target characteristics, the product needs to be folded and packed in a small limited space. In order to meet the re...

Abstract

The invention provides an omni-directional corner reflector for radar scattering feature enhancement and a verification method. The corner reflector comprises a plurality of set square corner reflectors. An inflation rod made of wave-transmitting material is disposed, through thermal sealing, at the outer contour of each set square corner reflector. After heat sealing of each inflation rod, air taking up 10% of the shaping volume of the inflation rod is filled in, and thereby the inflation rods can be inflated by the air filled in. The inflation rods are made of rubber coated terylene fabric materials for heat sealing, and the set square angle reflectors are made of ultra-thin and ultra-light aluminized terylene fabric. The invention is advantageous in that by adopting the form of the omni-directional angle reflector, the problem that an RCS mean value of a target feature control product is improved substantially can be resolved under the condition of limited quality and filling space;weight is light, volume is small, and the occupied filling space is small.

Description

technical field [0001] The invention relates to an omnidirectional angle reflector for enhancing radar scattering characteristics and a verification method. Background technique [0002] According to the product development background of a certain project, a target feature control product with large radar scattering characteristics is required. The average value of its radar cross section (RCS) is several times that of previous similar products. The size and quality greatly exceed the index requirements, and cannot meet the requirements of the filling space. Contents of the invention [0003] The technical problem solved by the present invention is: to overcome the deficiencies of the prior art, provide an omnidirectional angle reflector and a verification method for enhancing the radar scattering characteristics, within the range of the incident angle of radio waves ±180°, the RCS mean value of the target feature control product It meets the fluctuation range of 1.4㎡~2.8...
