METHOD FOR DETECTING VEHICLE WHEEL Russian patent published in 2017 - IPC G01S13/58 

FIELD: transportation.

SUBSTANCE: detection is performed by emitting the electromagnetic measuring beam (6), registering the frequency of the reflected measuring beam (6) over time as the received signal (E), and detecting changes (10, 11, F) of a particular type in the received signal (E) as the wheel (1), wherein an on-board device (15) is installed in the vehicle (2), in which information (D) is stored, determining, at least, the indirect vehicle length (L). This method provides reading the said information (D) from the on-board device (15) via radio (23) and by measuring the speed (v) of the vehicle (2); calculating the duration (T_F) of the vehicle passing (2) by the detection unit (5) based on the above information (D) and the speed (v); determining the time interval (W) in the received signal (E), demonstrating an approximately constant change (9) for the said duration (TF); determining the parasitic signal element (27) in the segment (25) of the received signal (E) immediately preceding the given time interval (W); and compensating the received signal (E) in the time interval (W) by the value of the signal parasitic element (27).

EFFECT: increasing the detection reliability and efficiency of the signal evaluating process.
