An Analysis of Wideband Beamforming Techniques and Hardware Requirements for Analog and Digital Radar Architectures


Due to the growing complexity and increased capability of radar systems, various enhancements to the design and testing of radars need to be considered. This project will focus on the understanding of implementations of analog, hybrid, and fully-digital radar architectures such as phased antenna arrays, antenna subarrays, and digital MIMO arrays. In addition, the project will include the evaluation of the performance of various established wideband beamforming algorithms in terms of their capabilities in nulling and frequency invariance in the presence of nonlinearities, caused by the use of wideband signals. This will also include implementations of several algorithms and evaluations of the effects of finite precision due to the limited resolutions of ADCs and phase shifters.
