| Abstract | ||
| This paper deal with studying speckle characteristic, (the main problem in coherent images), some digital techniques for simulation have been presented in this paper to generate noise similar to speckle noise, these done by adopting techniques by using Chi-square, 2-Gaussian, Multi Method, and Sinusoidal with different number of looks (1 to 5 look). Images can be simulated by multiplying, point to point, an in coherent image array by the simulated speckle data file. The size of the image and the speckle file must be equals. | ||
