Adaptive algorithm for Doppler ambiguity resolution in multiple target situations

An adaptive algorithm for velocity ambiguity resolution in coherent pulsed Doppler imaging system using multiple repetition frequencies (PRFs) is presented. The fast implementation of this unambiguous estimation procedure is based on the fast Fourier transform (FFT) of the nonuniformly sampled data...

Zusammenfassung:An adaptive algorithm for velocity ambiguity resolution in coherent pulsed Doppler imaging system using multiple repetition frequencies (PRFs) is presented. The fast implementation of this unambiguous estimation procedure is based on the fast Fourier transform (FFT) of the nonuniformly sampled data using two consequently changed PRFs. The proposed algorithm resolves the multiple undersampled waveforms and can be easily processed in the real-time Doppler processing.
