Abstract. The threshold method for
measuring of motion speed of the extended object within detection area of the
short-range radio location device reviewed and analyzed. It is shown that the using
additional speed measurement channel therein not only allows to detect the
extended object, but also allows to measure it’s motion parameters. It is shown that applying of the Doppler signal in the amplitude selection channel can
significantly reduce the phase noise, thereby increasing the accuracy of speed measuring of the extended object.
An estimation of the potentially achievable object speed measurement accuracy
of the short-range location devices is obtained.
