Mechanism Analysis And Simulation Study Of Aerial Stealth Curtain Wall For High-value Target Protection

In the fierce battlefield confrontation,being found by the enemy’s electronic reconnaissance system to expose the target almost means the failure of the combat mission.In order to weaken the combat performance of the enemy’s electronic system and avoid the loss of our combat plan,all countries have increased the theoretical research of various electronic jamming mechanisms and the design and application of jamming weapons.Correspondingly,electronic warfare or electronic countermeasure has become an important form of operation in modern war and an important aspect of the contest of national military strength.On the basis of traditional jamming weapons,this subject creatively puts forward a new concept weapon: stealth shield bomb and stealth curtain wall,which is produced by the combination of passive jamming,stealth materials and guided dispenser,so as to improve the battlefield concealment ability and mobile survivability of our weapons and equipment.Based on the transmission line theory of electromagnetism,combined with the relevant knowledge of stealth materials and radar,this paper deduces the interference mechanism of stealth curtain wall,and uses a variety of simulation means to analyze and simulate it,so as to realize the demonstration of the interference effect of stealth curtain wall and the feasibility of its battlefield application,which provides a scientific basis for the next research.The innovative methods and concepts proposed in this paper can also provide reference for the research and demonstration of other new concept weapons.The specific work of this paper is as follows:Firstly,this paper introduces the background of electronic jamming,systematically summarizes the advantages and disadvantages of conventional passive electronic jamming weapons at home and abroad and the research on wave absorbing electronic jamming,especially the current situation of jamming bombs carried by air fighters.What’s more,the research significance and key problems of stealth curtain wall are discussed comprehensively.On the basis of transmission line theory,absorbing mechanism and radar principle,the whole absorbing body is taken as the research object to model the mechanism of stealth curtain wall.Firstly,according to the electromagnetic wave propagation theory and the principle of energy conservation,the transmission loss and reflection loss models of the absorber surface are established,the effects of the absorber thickness,radar power,material characteristics and radar band on the effect are studied,and the absorption effects of the force and electrical characteristics of the curtain wall on electromagnetic waves in different bands are explored.Then,combined with the radar equation,the specific process of radar from transmitting electromagnetic wave to receiving target echo is analyzed,the echo power attenuation model is established,and the change of radar maximum operating range after jamming is obtained.Based on the absorbing characteristics of the stealth curtain wall,the modeling and simulation are carried out,including the analysis and verification of the electromagnetic performance of the absorber and the exploration and evaluation of the radar jamming performance of the stealth curtain wall.The specific work is to simulate the above model by using Ansoft HFSS and MATLAB phased array toolbox,simulate and verify the electromagnetic characteristics of stealth jamming curtain wall,simulate and analyze and evaluate the efficiency of stealth curtain wall in modern radar electronic warfare,establish evaluation standards and evaluate the combat effectiveness.On the basis of simulation,this paper attempts to design the structure of stealth shield bomb,and puts forward the use schemes of shield bomb based on different scenes.At last,the simulation results show that the stealth curtain wall scheme is feasible and has important popularization value and obvious military benefits.
