Study of synthetic aperture radar and automatic identification system for ship target detection

Automatic Target Detection and Recognition Using Synthetic Aperture Radar Imagery

Importance of Image Exploitation Defence forces rely upon a variety of sensor information to locate and track oppositional forces; the surveillance problem becomes particularly difficult over large land areas with sparse population centres and over the great expanse of the seas. The modern warfighter is dependent upon several types of image data to aid in the surveillance task including optical...

Synthetic Aperture Radar (sar) Automatic Target Recognition (atr) Parametric Study

sea target detection in polarimetric synthetic aperture radar images

study on polsar target detection essentially requires the cattering information and polarimetric statistical data. theoretical analysis shows that some terms of the second order scattering matrices such as coherence and covariance matrix clearly show the differences between nonsymmetrical man-made objects and natural clatters which being reflection symmetric. using the model derived from these ...

Cauchy - Rayleigh CFAR for Ship Detection in Synthetic Aperture Radar

Synthetic Aperture Radar (SAR) has over the years evolved to be one of the most promising remote sensing modalities for largescale monitoring of the ocean and maritime activity. The use of SAR imagery in a variety of monitoring applications has motivated significant research on the statistical modelling of such images, with recent work focusing on the ability of the data’s heavy-tailed nature t...

The Object Detection Efficiency in Synthetic Aperture Radar Systems

The main purpose of this paper is to develop the method of characteristic functions for calculating the detection characteristics in the case of the object surrounded by rough surfaces. This method is to be implemented in synthetic aperture radar (SAR) systems using optimal resolution algorithms. By applying the specified technique, the expressions have been obtained for the false alarm and cor...
