dc.description.abstractENGLISH ABSTRACT: This project investigates the improvement of an existing radar system by means of currently available technologies and signal processing techniques. Upgrades are aimed to improve the system's speci cations with focus on range resolution. Pulse compression and Doppler processing techniques are used to accomplish the improvement in range resolution. The use of pulse compression however resulted in numerous modi cations to the RF sub-system required by the introduction of Direct Digital Synthesizer modules. A full replacement of the existing signal processor with a Doppler processing based signal processor implemented on a single programmable rmware device was designed. Certain sections of this signal processor were implemented and tested. Pulse compression was successfully implemented and tested in both the transceiver and signals processor sections.en_ZA
dc.description.abstractAFRIKAANSE OPSOMMING: Hierdie projek ondersoek die verbetering van 'n bestaande radar stelsel deur gebruik te maak van huidige tegnologie en seinverwerking tegnieke. Aanpasings is gemik om die radarstelselspesi kasies te verbeter met die fokus op afstandsresolusie. Pulskompressie en Doppler- lter tegnieke is gebruik om 'n verbetering te maak aan die afstandsresolusie van die stelsel. Die gebruik van pulskompressie het 'n groot aantal veranderings aan die RF-stelsel genoodsaak a.g.v. die gebruik van Direkte Digitale Sintetiseerder modules. Die huidige radarseinverwerker is volledig vervang met 'n Doppler gebaseerde verwerker. Hierdie verwerker is volledig ontwerp op 'n enkele programmeerbare fermatuureenheid maar slegs sekere gedeeltes is getoets. Pulskompressie is suksesvol toegepas en getoets in beide die RF-stelsel en in die gedeeltes van die radarseinverwerker wat getoets is.af
