Embodiment Construction

[0030] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The description of the exemplary embodiments is for the purpose of illustration only, and in no way limits the invention and its application or usage.

[0031] Such as figure 1 As shown, the absorbing material for radar stealth according to the present invention includes: a metal base reflective layer 1, a surface absorbing suppression layer 2, an impedance matching layer 3, an intermediate heat-proof wave-absorbing layer 4, and a surface anti-wave absorbing layer arranged sequentially from bottom to top. Heat absorbing layer 5. By adopting a multi-layer absorbing structure and following the principle of electromagnetic wave space transmission impedance matching, when the electromagnetic wave is incident into the multi-layer structure, it gradually enters and attenuates layer by layer. Considering the different scattering mechanisms of electrom...

Abstract

The invention discloses a wave absorbing material for radar camouflage and a preparation method thereof. The wave absorbing material for radar camouflage comprises a metal substrate reflection layer, a surface wave absorbing restraining layer, an impedance matching layer, a middle heat-proof wave absorbing layer and a surface heat-proof wave absorbing layer, all of which are sequentially arranged from bottom to top. The wave absorbing material for radar camouflage and the preparation method thereof are low in cost, simple in process and suitable for industrial production, and the defects that a traditional wave absorbing material is narrow in camouflage frequency band, high in weight and large in thickness, the wave absorbing mechanism is single, the electromagnetic wave space impedance matching level and the dielectric loss capacity are low, and the wave absorbing performance in the high-temperature environment is suddenly reduced and even completely lost can be overcome.

Description

technical field [0001] The invention relates to the field of stealth technology, in particular to a wave-absorbing material for radar stealth and a preparation method thereof. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] Radar is the main means to detect, track and identify incoming missiles and guide interceptors. Therefore, radar stealth is the basic measure to improve missile penetration capabilities. According to it, the reduction of RCS after the missile is invisible can reduce the detection range of the opponent's anti-missile system radar, delay the time for the enemy's defense system to find our target, and reduce the probability of the warhead being tracked and intercepted without affecting the missile control system. At the same time, it also provides a basis for the warhead to use passive and act...
