Since their inception in 1935, relative ionospheric opacity meters (riometers) have evolved through several generations, from simple, manually operated, widebeam receivers to automated multi-beam, imaging riometers. This thesis follows the development of a new type of imaging riometer based on a Mills Cross antenna array: the Advanced Rio-Imaging Experiment in Scandinavia (ARIES). This is the first time that a digital cross-correlation beamforming technique has been used in riometry. The investigations presented cover initial simulations, software specification, design and implementation, hardware prototyping, the working instrument and first data products. Therefore, the work is an interdisciplinary slice through the engineering cycle of ARIES, encompassing a variety of subject areas, including (Space Plasma) Physics, Electronics, Astronomy and (Software) Engineering.
