Abstract

Most of the existing ISAR algorithms are based on the Fourier transform. However, for long coherent integration time or for fast maneuvering targets, simple Fourier processing without compensation will lead to severe blurred and distorted image. The standard techniques for these kinds of problems are motion compensation process or time-frequency analysis application. These two types of techniques are computationally intensive. This paper presents a numerically simple s-method based approach. The efficiency of this proposed method is demonstrated on simulated aircraft data sets
