Abstract
According to the principle of X-ray coded aperture imaging,the ground simu-lation imaging system was set up.On the basis of it,the theoretical calculation method of the yield and the orientation of near-earth space nuclear explosion was established.The relationships between the system response(gray value)and the intensity of X-ray, the center of mass coordinates of the reconstruction imaging and the X-ray incidence angle were presented,and the nuclear explosion yield and orientation simulation detec-tion experiments were carried out.The experimental results are consistent with the the-oretical calculation results,so the feasibility of using X-ray coded aperture imaging tech-nology in near-earth space nuclear explosion detection is verified.Compared with multi-pinhole imaging system,X-ray coded aperture imaging system has higher detection sensitivity,signal-to-noise ratio and anti-jamming ability.关键词
