Software infrastructure is a growing part of modern radio science systems. As part of developing a generic infrastructure for implementing Software Radar systems, we have developed a set of reusable signal processing components. These components are generic software based implementations for use on general purpose computing systems. The components allow for(More)
Atmospheric scientists need to observe fluctuations in the ionosphere, both to probe the underlying atmospheric physics, and to remove the effects of these fluctuations from other measurements. We have built an FPGA-based, pipelined array processor that allows us to make these observations in real-time, using passive radar techniques. Our array processor(More)
The process of scientific discovery is traditionally assumed to be entirely executed by humans. This article highlights how increasing data volumes and human cognitive limits are challenging this traditional assumption. Relevant examples are found in observational astronomy and geoscience, disciplines that are undergoing transformation due to growing(More)
The Radio Array of Portable Interferometric Detectors (RAPID) is an advanced radio instrument designed for a diverse range of scientific applications including radio astronomy and geospace imaging radar. RAPID aims to employ physically disconnected arrays of antennas, which can capture raw voltage data to process post-experiment. The signal processing for(More)
The Radio Array of Portable Interferometric Detectors (RAPID) is an advanced radio designed for multi-role applications. The system implements a spatially diverse sparse array technology and can be deployed and reconfigured easily. Data are captured at the raw voltage level using the system in the field and processed post-experiment. Signal processing for(More)
1.0 Introduction The Geospace Array is a next generation digital radio array capable of active and passive measurement of the Geospace environment. The system would be deployed globally to provide ground based measurement of fundamental physical parameters in the Geospace environment. The system will address science topics from the lower atmosphere to the(More)
We briefly describe two new Incoherent Scatter Radar designs which take advantage of recent technological advances in Software Radar technology and high power UHF transmitters. The Zenith Incoherent Profiler (ZIP) is designed to produce vertical measurements of ionospheric properties on a 24/7 basis for use in assimilative models and real-time Space Weather(More)
