    Abstract

    This thesis developed a calibration and imaging strategy for 300MHz MWA observations. Due to highly sensitive grating sidelobes MWA observations in this high frequency regime until now have been largely unprocessed. This thesis uses a model of the sky at 300MHz with a model the MWA beam at 300MHz to calibrate MWA observations. Deep images of calibrated observations were created by subtracting out the grating sidelobes. These are the first deep MWA images at 300MHz.
