Contributions in inverse synthetic aperture radar imaging

Abstract

The area of work chosen is Inverse Synthetic Aperture Radar (ISAR) imaging as ISAR images provides an extremely useful application, that is, for the purpose of surveillance and target recognition. The focus of our work is to tackle several important issues that have not been resolved till now. The thesis proposed methods to solve these issues so as to improve the quality of ISAR images. The two major contributions are in the area of array-based ISAR imaging and imaging of targets exhibiting the micro-Doppler phenomena. The detailed discussions include a three-dimensional inverse synthetic aperture radar imaging method using an antenna array configuration and sparse array imaging. Micro-Doppler extraction methods and imaging of a helicopter target is also discussed.
