What is Noise Reduction

Chapter 17
Handbook of Research on Advanced Trends in Microwave and Communication Engineering
Reduction of superfluous information (noise) from the images. Speckle noise is the high frequency component and it reduces the contrast of the radar images. Suppressing the effect of speckle noise improves the accuracy of the classification task.

Abstract
In this chapter, Inverse Synthetic Aperture Radar, a special type of active microwave synthetic aperture radar is introduced and its applications in military surveillance are presented. Then, the basic principles involved in data acquisition and image generation are explained. The issues and challenges involved in processing the ISAR images for autonomous target detection and identification are discussed later. The proposed classification method is explained and its accuracy is evaluated experimentally against the conventional classification method in the rest of the chapter.
