الملخص الإنجليزي

Satellite images record electromagnetic radiation intensity that emitted or reflected from Earth's object within the field of view (FOV) of satellites imaging sensor.

These radiations are affected by the turbulent atmosphere and other effects (like noise and motion detectors), thus will reduce the quality of acquired images.

Since the degree of distortion depends on wavelength, and since satellite images are taken in different wavelengths (multispectral bands) including visible and infrared (emitted and reflected).

Each band of satellite images will have different value of distortion.

In this work, computer program using matlab language, have been written to study a degradation effect parameters for each band of Landsat7 satellite image are studied.

The objective is to show which one is the best from others (vegetation, water and sand areas are used in this work).

We found that band3 (l =0.630-0.690mm), band4 (l =0.750- 0.900mm) and band7 (l =3.090-2.350mm) are the best one for vegetation, water and sand area respectively.

Archive of these areas is build up to estimated parameters used for recovery other images.

Good results are obtained when the size of the recovered area is small.
