ABSTRACT:
A method and system is disclosed for remote all-weather monitoring of civilian road traffic over large portions of a metropolitan region, using one or more microwave radar systems situated at elevated locations, such as high towers or pilotless aircraft. Pulse-Doppler waveforms provide, for each position of the radar beam, range-velocity maps of traffic over a number of selectable roadway sections, which maps are used to estimate the speed, density, and volume of traffic flow and to identify discontinuities in the flow which may be indicative of accidents or obstructions. In addition, a high-resolution wideband waveform can be included to provide detailed examinations of selected portions of the monitored roadway sections.
