A Digitized Radar for Precipitation Measurements and Applications to Hydrology.

摘要

The major objective of this research project was to design a digital processor to interface a meteorological radar with an on-line minicomputer and CRT graphic terminal. The resulting system will be used to measure precipitation in real time and to monitor severe storms. The processor is designed to process the radar image into range-azimuth cells and transfer an integrated image intensity for each cell to computer memory. After transfer to memory,the intensity data is converted to precipitation rate and cumulative precipitation by computer software. Capability will also be provided for recalling the image or other data for display on a CRT graphic terminal. For convenience in design and assembly the processor was divided into two units, a video integrator and A/D converter unit and a radar computer interface unit. The general characteristics of these two units are summarized in this report.
