Abstract: Abstract- The Researchers uses Satellite images for their Research work in many fields. The Satellite images have issues with their resolution. So, the images which loses their high frequency contents. And they appeared as blurred image. This paper proposes a resolution enhancement technique called Multi Wavelet Transform (MWT). This technique obtains the interpolation of high frequency sub bands and low resolution input image. The MWT uses Discrete Wavelet Transform (DWT) to split the image into sub bands. Then high frequency sub band images are obtained and the input images have been interpolated. Finally the inverse MWT have been applied to generate the enhanced high resolution satellite image. This paper analyses the performance of various image resolution techniques for satellite images. The proposed technique produces less artifacts with less Mean Square Error and increased values of Peak Signal to Noise Ratio
