A wavelet-based ammunition doppler radar system
Today’s state-of-the-art ammunition Doppler radars use the Fourier spectrogram for the joint time-frequency analysis of ammunition Doppler signals. In this paper, we implement the joint time-frequency analysis of ammunition Doppler signals based on the theory of wavelet packets. The wavelet-based approach is demonstrated on Doppler signals for projectile velocity measurement, projectile inbore velocity measurement and on modulated Doppler signal for projectile spin rate measurement. The wavelet-based representation with its good resolution in time and frequency and reasonable computational complexity as compared to the Fourier spectrogram is a good alternative for the joint time-frequency analysis of ammunition Doppler signals.
