Phased array antennas--Design and construction, Monopulse radar
Abstract
Phased array antennas are widely used around the world. Much research is focused on extending capabilities of modern wireless systems and radars. Dual-mode elements are researched for use in beamforming, monopulse radar and multi-frequency applications. Beamforming in itself is an extensively researched topic, aimed at canceling interference and/or finding signal angle-of-arrivals. The goals of this thesis are two-fold. Firstly, to take the monopulse capabilities of a dual-mode antenna element to allow for a linear phased array antenna to generate the sum, delta-azimuth, and delta-elevation channels whereas normal linear phased array antennas can only generate a single difference channel. Secondly, to exploit the signal separating abilities of eigen-space methods to improve the performance of monopulse in a scenario where there is a closely correlated target corrupting the data. Future work should investigate array designs using multi-mode elements and further studies of any extra capabilities such an element brings to adaptive processing.
