Author:Herselman, PL; Cilliers, Jacques EDate:27 Feb 2006This paper presents the Digital Instantaneous Frequency Measurement (DIFM) technique, which can measure the carrier frequency of a received waveform within a fraction of a microsecond. The resulting frequency range, resolution and accuracy ...Read more
Author:Herselman, PL; Nel, Willem AJ; Cilliers, Jacques EDate:Feb 2006In this research, the critical implications of the phase response of a Digital Radio Frequency Memory (DRFM) based repeater system on the Doppler spectrum of a modern, coherently processing radar system (for example pulsed Doppler radar) are ...Read more
Author:McDonald, Andre M; Van Wyk, MADate:Sep 2018A novel random signal generator design that accommodates the specification of both the sample probability distribution as well as the signal bandwidth is presented in this paper. The generator achieves a high degree of computational efficiency ...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
