Author:Strydom, JJ; De Witt, JJ; Cilliers, Jacques EDate:Oct 2014This paper describes a simple process for the generation of arbitrary probability distributions of complex data with correlation from sample to sample, optimized for hardware in the loop radar environment simulation. Measured radar clutter ...Read more
Author:Cilliers, A; Nel, Willem AJDate:Sep 2008A technique based on time-frequency and tomographic analysis to extract helicopter blade parameters for the purposes of radar non-cooperative target recognition (NCTR) is investigated. The proposed algorithm shows that (under certain conditions) ...Read more
Author:Venter, CJ; Grobler, H; AlMalki, KADate:Dec 2011The Cell-Averaging Constant False-Alarm Rate (CA-CFAR) algorithm was implemented and optimized in software on the NVIDIA Tesla C1060 GPU architecture for application in pulsed-Doppler radar signal processors. A systematic approach was followed ...Read more
Author:Herselman, PL; De Wind, HJDate:Sep 2008Asymptotically optimal coherent detection techniques yield sub-clutter visibility in heavy-tailed sea clutter. The adaptive linear quadratic detector inherently assumes spectral homogeneity for the reference window of the covariance matrix ...Read more
Author:De Villiers, JP; Cronje, J; Nicolls, FCDate:Apr 2011Inverse lens distortion modelling allows one to find the pixel in a distorted image which corresponds to a known point in object space, such as may be produced by a RADAR. This paper extends recent work using neural networks as a compromise ...Read more
Author:Focke, RDate:Dec 2009This paper presents a scalable solution utilising FPGAs for high performance data processing. Part B of the paper covers topics relating to firmware and software development.Read more
Author:Mkwelo, SimpiweDate:Oct 2015This presentation discusses the roles and uses of radar, radio frequency electronic warfare and optronics as operational defence systems.Read more
Author:Blaauw, Ciara; Potgieter, Monique; Cilliers, Jacques EDate:Apr 2020Commercial off the shelf antennas make it possible to perform rapid initial system tests and proof of concepts experiments. This paper reports on the antenna performance of a cost effective commercial off the shelf printed Log-periodic antenna ...Read more
Author:Botha, L; Gaffar, YADate:Feb 2006The study, by CSIR Defence, Peace, Safety and Security is using propagation prediction software to predict the propagation effects of both communication and radar systems. These are the models used in the study: Free Space Model; Rn Model; ...Read more
Author:Anderson, FDate:Nov 2008South Africa, like other countries, faces the challenge of protecting its territory and its people from activities such as illegal border crossings, weapons trafficking, smuggling, piracy, poaching, organised crime, and terrorism on land, at ...Read more
Author:Combrink, CJ; Venter, CJ; Govender, S; Alshareef, MADate:May 2011A reconfigurable Control and Monitoring Framework (CMF) was developed, integrated and tested with a Radar Signal Processor (RSP). The methods and processes used to develop and utilise the CMF are highlighted in the context of a complete Control ...Read more
Author:Shikwambana, L; Sivakumar, V; Sharma, AmeethDate:Jul 2012LIDAR is an acronym for light detection and ranging, it is analogous to radar (radio detection and ranging), except that it is based on discrete light pulses and measured travel times. We report on the mobile LIDAR system developed at the ...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
