U ovom radu se predlaže algoritam za estimaciju putanje više radarskih meta u okolini jakog šuma. Primjenom algoritama iz oblasti vremensko-frekvencijske analize je moguće dobiti range-doppler reprezentaciju radarske mete u jednom vremenskom trenutku. U sekvenci sukcesivnih vremenskih trenutaka je takođe i sadržana informacija o promjeni položaja radarske mete. Uticaj jakog šuma èesto može da dovede...
An algorithm for radar signal detection method based on a time-frequency representation (TFR) and Viterbi algorithm (VA) is proposed. Two TFR methods are considered, Short-time Fourier Transform (STFT) and S-method (SM). Performance and detection ability of the proposed algorithm was investigated on real radar signals of a single manuvering target with added Gaussian noise and signal-to-noise ratio...
In this paper, it is demonstrated that time-frequency techniques may be used for an enhanced diagnosis of the heart disease. Three time-frequency analysis techniques are compared: spectrogram, Wigner distribution and S- method. The results show that the S-method could be used in the heart sounds analysis, and that is also capable of enhancing the diagnostic techniques available to medical personnel.
