doppler-shift

Python tool for aircraft Doppler audio geolocation using historical ADS-B flight data (Source-available)

Find out where an audio recording was made. Planes flying past leave a faint engine hum whose pitch drops as they go by. AeroDoppler compares those pitch changes with public records of where planes actually flew, and works out where the microphone must have been.

Audio UI is a Swift iOS experiment in Ultrasound based gesture recognition on iOS.

Interactive radial-velocity and Doppler-spectroscopy observatory connecting stellar spectra, wavelength shifts, orbital motion and exoplanet signals with the measurement challenges of precision radial-velocity astronomy.

MATLAB simulations of hostile wireless channels: Rayleigh fading, Doppler, delay spread, DBPSK and OFDM modulation, BER vs SNR/bitrate analysis.

End-to-end MATLAB analysis of RS-44 sattelite using TLE/SGP4 orbit propagation, Doppler modeling, CW Morse beacon simulation, FFT/STFT, and radial-velocity estimation.
