Threshold method of measurement of extended objects speed of radio engineering devices of short-range detection

The threshold way of measurement of speed of movement of extended objects is considered and analyzed. It is shown that implementation of an amplitude threshold allows to reduce more than two-times values of dispersion of estimates of speed in a wide band of frequencies and to lower all spectral components of phase noise. The fact of exponential reduction of spectral density of this noise up to zero with threshold growth is especially important. The carried-out theoretical and numerical analysis allows to give estimates of potentially achievable accuracy of measurement of extended objects movement speed.
