Author:Lord, RT; Nel, Willem AJ; Abdul Gaffar, MYDate:May 2006Conventional Inverse Synthetic Aperture Radar (ISAR) utilises the rotational motion of a target such as a ship or an aircraft to obtain a 2-D image of the target’s radar cross section (RCS) profile from a coherent radar system. This concept ...Read more
Author:Kathree, U; Nel, Willem AJ; Van Rensburg, VJ; Mishra, AKDate:Oct 2015In the field of radar, High Range Resolution (HRR) profiles are often used to improve target tracking accuracy in range and to allow the radar system to produce an image of an object using techniques such as inverse synthetic aperture radar ...Read more
Author:De Freitas, A; De Villiers, Johan P; Nel, Willem AJDate:Jun 2015A target of interest measured by a high range resolution radar may be modelled by multiple dominant points of reflections referred to as dominant scatterers. In this study a non-linear state space setting is used to model the states and ...Read more
Author:Abdul Gaffar, MY; Nel, Willem AJ; Inggs, MRDate:Oct 2008Inverse synthetic aperture radar (ISAR) is an imaging technique that is dependent on an object’s rotational motion over a coherent processing interval. Maritime vessels and aircraft possess 3-D rotational motion, whereas it is only their ISAR ...Read more
Author:Steyn, JM; Nel, Willem AJDate:Oct 2014Most research efforts in ISAR focus on techniques to form the image via autofocus or on classification (assuming that the ISAR imagery is already generated). An important step between image formation and classification is to determine which ...Read more
