A strong understanding of the spatial and temporal variation of the Earth's ionosphere (a magneto-ionic, refractive medium 50–1000 km above the Earth's surface) is paramount for the effective operation of radio systems for communication. Ionospheric measurements can be assimilated into models, such as the Electron Density Assimilative Model (EDAM) to produce three-dimensional global nowcasts of the...
A real-time automatic vehicle correlator system that is capable of identifying the make, model, and series of road traffic, e.g., a Volkswagen Golf Mark 4, has been implemented in field-programmable gate array (FPGA) hardware housed on a peripheral component interconnect (PCI)-format electronic board. The system is compatible with standard desktop personal computers and accepts imagery from networked...
