UnverifiedThe inflection point of the Doppler curve corresponds to the moment the aircraft is closest to the observer, at which the frequency shift is zero.69% similarUnverifiedDoppler frequency reflects the rate of change over time of the bistatic path length and is related to the target's radial velocity component.65% similarUnverifiedThe linear velocity of Earth's rotation is highest at the equator, at approximately 465 meters per second.65% similarUnverifiedCombining ADS-B trajectory data (including the aircraft's position, speed, altitude and timestamps), the observer's geometric position relative to the aircraft's trajectory can be inferred.60% similar
