Data fusion method of airborne radar mapping and remote sensing image information based on wavelet transform
in the process of fusion airborne radar surveying and mapping remote sensing image information data,due to the original airborne radar surveying and mapping remote sensing im-age feedback signal in the frequency domain distribution,the quality of the fusion image is rel-atively low,therefore,this paper puts forward the method of airborne radar remote sensing im-age information data fusion based on wavelet transform.The method sets the window function based on frequency in the wavelet transform,and combines the relationship between the fre-quency domain and the state of the frequency function,and establishes the product relationship between the distribution parameters of the remote sensing image signal and the frequency win-dow.The test results showed that the post-fusion images were at high levels in terms of com-pleteness,clarity and integrated quality.
