dc.description.abstractThe objective of this thesis is to investigate a Wideband Leakage Cancellation Circuit (WLCC) to facilitate potential improvement of range resolution in single antenna Frequency Modulated Continuous Wave (FMCW) radar, as well as other applications. The research has successfully extended the operating bandwidth of a basic single frequency LCC by the use of a Frequency Demultiplexing and Multiplexing Circuit (FDMC) consisting of a bank of N leakage cancelling branches. The WLCC was designed, tested and evaluated through a low risk and cost-effective approach, using an electronic-design automation software system known as the Advanced Design System (ADS) 2009 developed by Agilent Technologies. The WLCC was successfully evaluated by benchmarking its performance against that of a single frequency Leakage Cancellation Circuit (LCC), both with ideal and non-ideal component parameter settings. The robustness of the WLCC was also evaluated by a series of simulations with antenna load mismatch conditions. Future work and development was proposed on the current WLCC design to support ongoing NPS research on the Wirelessly Networked Distributed Digital Phased Array (WNDDPA).en_US
