The usage of algebraic iteration imaging method in radar imaging

Abstract

Inverse synthetic aperture radar (ISAR) imaging is a useful method of target identification in radar detection. However, rapidly rotating parts, such as propellers and blades on aircrafts, cannot be focused by conventional imaging algorithm. In this paper, we introduce a novel method for imaging rapidly rotating targets by wideband radar. This method is an algebraic method which is based on building and solving equations. Simulations are presented to demonstrate the effectiveness of these methods.
