Abstract

This paper considers a ship detection in synthetic aperture radar (SAR) systems constructed on the basis of generalized detector (GD). To obtain better results without ambiguity it is better to use multi-channel SAR with more than two antennas. However, there are very few SAR systems with more than a single antenna, which is because of the complexity and immense data rates produced by multi-channel systems. So, it is preferred to use single channel SAR systems. In this research a single channel Envisat image is considered, in order to have more accurate result the symmetrical sub-aperture images (multi-look) are obtained from splitting a 1024×1024 part of Envisat image. The GD which is a combination of the Neyman-Pearson detector and the energy detector is applied on three separate sub-apertures with a limited number of ships. The intensity of pixels are compares with the GD threshold to make a decision statistics under hypothesis H0 and H1 to find ships in the sub-apertures.
