Image encryption method and module based on improved two-dimensional logistic mapping, and radar communication system

The invention relates to the technical field of image processing and transmission, in particular to an image encryption method and module based on improved two-dimensional logistic mapping and a radar communication system. According to the method, improved two-dimensional logistic mapping is provided, chaotic image encryption is carried out based on two chaotic sequences generated by the improved two-dimensional logistic mapping, a chaotic image encryption method combining cyclic shift and global diffusion is provided, and the encryption effect is better. Through simulation comparison, compared with the traditional two-dimensional logistic mapping, the method disclosed by the invention has the advantage that a plurality of encryption indexes are improved. According to the invention, the image encryption method based on improved two-dimensional logistic mapping is applied to a radar communication system, and a set of image secrecy radar communication system is designed, so that the specific application of the
