Segmentation-based target detection in SAR
This paper proposes a target-detection scheme based on prior segmentation of the image. Introducing the prior knowledge of image structure provided by the previous segmentation eliminates many false target detections from background structure. The performance of the new scheme is shown to be identical to an ideal one-parameter CFAR for constant background. With real clutter backgrounds the back...
متن کاملA Novel Algorithm for Ship Detection in Envisat Sar Imagery Based on the Wavelet Transform
Carrying out an effective control of fishing activities is essential to guarantee a sustainable exploitation of sea resources. While traditional reconnaissance methods, such as planes and patrol vessels are indispensible, their operation is quite time consuming and costly over the extended regulated areas. On the contrary, satellitebased Synthetic Aperture Radar (SAR) provides a powerful survei...
متن کاملTarget Detection and Recognition in SAR Imagery Based on KFDA
--Current research on target detection and recognition from synthetic aperture radar (SAR) images is usually carried out separately. It is difficult to verify the ability of a target recognition algorithm for adapting to changes in the environment. To realize the whole process of SAR automatic target recognition (ATR), especially for the detection and recognition of vehicles, an algorithm based...
متن کاملMoving Target Detection on SAR Images
Synthetic aperture radar (SAR) is a well known technique for generating high-resolution images stationary scenes but it is not adapted to imaging moving targets as the movement of a target induces both a delocalization and a defocusing effect in a SAR image. The aim of this paper is to analyse the signatures of moving targets in SAR images and to present techniques to detect them, from one sing...
متن کاملIntrusion Detection based on a Novel Hybrid Learning Approach
Information security and Intrusion Detection System (IDS) plays a critical role in the Internet. IDS is an essential tool for detecting different kinds of attacks in a network and maintaining data integrity, confidentiality and system availability against possible threats. In this paper, a hybrid approach towards achieving high performance is proposed. In fact, the important goal of this paper ...
