Onboard signal processing, technology and systems. Volume 3: Signal processing applications
Abstract
Three separate reports, each describing a real-time processing system and discussing the applicability of advanced technologies to its implementation are presented. The first report is concerned with synthetic aperture radar (SAR) processing. Following a section dealing with the characteristics of the SAR signal, three sampled data system architectures suitable for performing the processing in real-time are introduced. Extensions to these architectures, required to allow range migration correction and subaperture processing to be performed, are then considered. Finally processor implementations are discussed based on a tentative specification. The second and third reports, describe the hardware implementation of the Karhunen-Loeve transform and a histogram clustering technique for image data compression, respectively. The main aim is to produce an implementation giving the lowest power consumption using advanced analog and digital technologies. The most promising approach seems to be a digital solution using custom SOS CMOS whereby an order of magnitude reduction, compared with present-day devices, can be achieved.
