Author:Melebari, A; Abdul Gaffar, MY; Strydom, JJDate:Oct 2015In modern radar systems with high range resolution, the statistical properties of clutter have a significant effect on the performance of the radar. Analyzing the radar returns from various clutter terrains is essential when aiming to optimize ...Read more
Author:Du Plessis, WP; Kitching, C; Bin Ghannam, ADate:Mar 2012The effect of allowing shared elements in interleaved thinned arrays is investigated. The sidelobe level (SLL) as a function of the number of shared elements mirrors the SLL of thinned arrays as a function of filling factor because the number ...Read more
Author:Strydom, JJ; Cilliers, Jacques E; Gouws, M; Naicker, D; Olivier, KDate:Oct 2012This paper describes the development and testing of a digital radio frequency memory (DRFM) kernel, as well as some of the functionality which has been added to the system to make it a fully-fledged hardware in the loop (HIL) radar environment ...Read more
Author:Botha, Louis; Kloke, Kevin H; Smit, Johan C; Kitching, CelmaDate:Jul 2016We have decided to develop some common building blocks for use in radar system at the CSIR, DPSS. The reasons for doing this are: a) The cost of ad-hoc- developed RF subsystems (using connectorised components) is getting to be prohibitive as ...Read more
Author:John, RS; Erasmus, Louwrence DDate:Jul 2020The objective of this study was to analyse the development of radar systems in a government research and development environment from a systems engineering perspective and identify which, if any, systems engineering tools and methods are used. ...Read more
Author:Wabeke, LO; Nel, Willem AJDate:Jun 2010Recent research show that utilization of knowledge of the environment can allow a radar system to adapt its processing to improve its performance. Furthermore, a radar system that utilize both a-priori and measured knowledge in an adaptive ...Read more
