| Summary: | Thesis (MScEng)--University of Stellenbosch, 2005. === ENGLISH ABSTRACT: The development of a radar system is a complex process, requiring a substantial amount of
testing. In general, these tests are performed using field trials. Such trials are expensive,
and their exact conditions can never be repeated. A radar environment simulator allows
for repeatable testing of the majority of a radar's functionality; however, most commercial
products are not cost effective. In this thesis we investigate the various approaches to
modelling targets and the littoral environment, and then develop a low-cost, largely software
defined simulator. This simulator is capable of generating real-time video signals for a
monopulse doppler tracking radar. The core simulation routines reside in an extensible
software framework which is populated with simple target and clutter models for a prototype
simulator. Closed loop tracking tests verify the operation of the prototype simulator. === AFRIKAANSE OPSOMMING: Die ontwikkeling van 'n radarstelsel is a ingewikkelde proses wat verskeie stelseltoetse benodig.
Veldtoetse, wat gewoonlik gebruik word, is 'n duur proses, en die toestande is nooit
presies dieselfde nie. 'n Radar-omgewingsimulator kan 'n groot deel van 'n radar se funksionaliteit
herhaaldelik toets. Daar is egter weinig koste-effektiewe kommersile produkte
vir hierdie doel beskikbaar. Hierdie tesis ondersoek verskeie teiken- en omgewingsmodelle,
waarna 'n lae-koste, meestal sagteware-gedefinieerde simulator ontwikkel word. Hierdie simulator
genereer intydse videoseine vir 'n enkelpuls-dopplervolgingsradar. Die kernfunksionaliteit
van die simulator is in sagteware gesetel, en basiese teiken- en omgewingsmodelle is
geïmplementeer. Die prototipe-simulator word getoets deur dit aan die radar self te koppel,
en dan die teiken-opsporing en -volging te verifieer.
