Study on protection effect of laser diffuse reflector
In order to scientifically evaluate the protective effect of the laser diffuse reflector in the laser angle deception jamming process,the coordinate transformation method was used to compare the energy density of the indicating laser received by the seeker and the jamming laser in the same coordinate system and the jamming coverage rate of the guidance airspace was calculated,and then the influence of the difference of the normal direction of the diffuse reflection plate and the target on the protective effect was analyzed.The research shows that for a typical-cubic type target,when the normal of the diffuse reflector is the same azimuth as the normal of the vertical plane of the target,and the pitch difference is between 0° and 60°,the guidance airspace jamming coverage of the vertical plane is 100％.Only when the normal direction of the diffuse reflector is the same as the normal direction of the horizontal plane at the top of the target the guidance airspace jamming coverage of the plane is 100％.In order to achieve comprehensive protection,it is necessary to set up multiple diffuse reflectors for protection according to the direction of the laser attack and the possible irradiated surface.This research method and results have reference values for reasonable layout and use of laser diffuse reflector.
