Development of a Distributed Digital Array Radar (DDAR)
MetadataShow full item record
Distributed digital arrays have many potential applications in radar and communication systems. The objective of this thesis is to re-examine previous research on distributed digital array radar (DDAR) and evaluate several critical aspects of a proposed wireless architecture. Self-standing transmit/receive (T/R) modules are synchronized wirelessly. An important issue addressed in this thesis is whether a simple low-cost synchronization circuit would perform adequately. To this end two breadboard T/R modules were built to support test and evaluation. Both measurements and simulations were performed. Other issues addressed in the research include a comprehensive investigation of the demodulator performance, and the development of Controller and processing software in LabVIEW.
