Abstract

Abstract:

This paper proposes a new approach for the SAR image detection of the target with a certain size and direction. We filter the SAR image with exponential wavelet directionally, based on its selective enhancement of SAR target edges. Then a novel term Exponential Wavelet Fractal (EWF) feature is defined considering the filtered target's characteristics. EWF can detect the SAR target using the priori information on the target size and direction. Different from most traditional SAR detections, EWF not only distinguishes target pixels from the background only based on the contrast, but also is sensitive to the object direction and size. The validity of the EWF method for the detection of targets with a known size and direction is evaluated based on the MSTAR data.

Key words: SAR image processing, automatic target detection, synthetic aperture radar, exponential wavelet, special target detection
