Estimation of spectral entropy for drone signal detection
4 views (last 30 days)
I need to find spectral entropy of a signal that have drone sound and some other noises.
After localization of sound signal, how can i confirm that which frames of signal have drone sounds only.
For that i need to do spectral or frequency entropy.
My work flow is like that:
reading signal in matlab >> framing with 50% overlapping of window>> FFT and choose real part >>
How can i seprate Drone sound from other noises to get farmes of only drone sound using Entropy function.
Please researches guide me for this query.
Thanks in advcance.
