Abstract:
Statistical characteristics of the density distribution of the instantaneous frequency of deep fading signals were defined. The threshold method for measuring of motion speed of the extended object within range radio measuring instrument movement device reviewed and analyzed. 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 is obtained.
