METHOD OF DETERMINING RANGE AND/OR SPEED OF REMOTE OBJECT Russian patent published in 2010 - IPC G08G1/52 G01S17/08 G01S17/58 

FIELD: measuring techniques.

SUBSTANCE: invention relates to measuring techniques and can be used particularly for detecting violation of traffic rules by a vehicle. The method involves multiple probing a remote object by sending a series of laser pulses towards it, determining in each probe of the lag between sending the pulses and receiving the radiation reflected by the object, analytical determination of the current range of the object and recording these range values. The series of probes with recording of time values is divided into two groups. For the first group of probes, linear interpolation of recorded range values is carried out, from the results of which the trajectory of the object is pre-determined. Depending on the determined speed value, a reference time interval is formed, at the end of which the second group of probes is carried out. A revised trajectory is determined from range and time instant values recorded in both groups of probes. When recording probe results and after determining the revised trajectory of the object, measurements of the range of the object, results of which differ from the previous reliable measurement value exceeding the limit error of range measurement, are cancelled. The revised trajectory of the object is re-determined from the remaining results which have been ruled reliable.

EFFECT: invention saves resources and increases service life of the device, and also reduces power consumption by cutting on the number of measurements in the series of probes with minimal error of determining speed of an object in a wide range of speed.
