By means of computer simulation, the influence of the processing of the receiving path of the navigation RTS on the structure of the signal reflected from a long object, which leads to the expansion of the spectrum of the reflected radio signal and the complication of measuring its Doppler frequency, was investigated. The adequacy of the simulation to the real observation of the signal and the possible influence on the characteristics of its contour and phase structure are analyzed.
