Abstract

This paper examines the sourcing of low cost components for next generation passive millimetre wave (PMMW) aperture synthesis imagers. Splitting the elements of the imager into antennas/receivers, analogue to digital converters (ADCs), digital signal processors (DSP) and a host computer, technologies are identified that can minimise the cost of these in future systems. It is established that the follow-on aperture PMMW imagers can be constructed at relatively low cost, using a combination of low frequency (< 30 GHz) satellite receiver technology, high-speed clocked comparators, DSP (both Field Programmable Gate Arrays (FPGAs) and Graphical Processor Units (GPUs)) and the latest personal computers that use high-speed high lane count PCI Express Bus technology.
