ISAR imaging using the instantaneous range instantaneous Doppler method

Author: Wazna, TM ; Balamesh, AS ; Abdul Gaffar, MY Date: Oct 2015 In Inverse Synthetic Aperture Radar (ISAR) imaging, the Range Instantaneous Doppler (RID) method is used to compensate for the nonuniform rotational motion of the target that degrades the Doppler resolution of the ISAR image. The Instantaneous ... Read more
Quality measures for HRR alignment based ISAR imaging algorithms

Author: Janse van Rensburg, V ; Mishra, A ; Nel, Willem AJ Date: May 2013 Some Inverse Synthetic Aperture Radar (ISAR) algorithms form the image in a two-step process of range alignment and phase conjugation. This paper discusses a comprehensive set of measures used to quantify the quality of range alignment, with ... Read more
Selecting suitable coherent processing time window lengths for ground-based ISAR imaging of cooperative sea vessels

Author: Abdul Gaffar, MY ; Nel, Willem AJ ; Inggs, MR Date: Sep 2009 Inverse synthetic aperture radar (ISAR) imaging of sea vessels is a challenging task because their 3-D rotational motion over the coherent processing interval (CPI) often leads to blurred images. The selection of the duration of the CPI, also ... Read more
Synthetic range profiling, ISAR imaging of sea vessels and feature extraction, using a multimode radar to classify targets: initial results from field trials

Author: Abdul Gaffar, MY ; Nel, Willem AJ ; Naicker, K ; Steyn, J ; Alanazi, T ; Alzamil, A Date: Apr 2011 This paper describes the design and working principles of an experimental multimode radar with a stepped-frequency Synthetic Range Profiling (SRP) and Inverse Synthetic Aperture Radar (ISAR) capability for the purpose of operator-based ...
