Vehicle speed measuring procedure, involves calculating theoretical function of evolution for speed and given angle alpha, and deducing searched speeds from selected Doppler frequencies that correspond to vehicle

摘要

The procedure involves identifying Doppler frequencies associated to vehicles situated in a field covered by a wave emitted by an antenna, in each Doppler signal obtained at successive instants. Theoretical function of evolution is calculated for a speed and a given angle alpha, based on time of the Doppler frequency that is associated with a vehicle. Searched speeds are deduced from selected Doppler frequencies. The selected Doppler frequencies correspond to the same vehicle. An Independent claim is also included for a device to install a procedure.
