要約

The research paper summarizes the theoretical results of the Doppler signal synthesis generated by underlying surface. It is demonstrated that the synthesized model can be represented as an amplitude-modulated in envelope and a frequency-modulated one in carrier. On the basis of the synthesized model computerized simulation was done, the results of which are shown as respective characteristic curves of the Doppler signal under consideration. Spectral analysis was performed by the fast Fourier transform method and represented as analytic spectrum in paper. Experimental results are in line with well-known data registered in the relevant references covering the issues of the Doppler signals processing.
