, used as an index of sternal skin stress, was recorded continuously as the subject performed three trials of each lift.
A true self-test must verify both the transmitter's operation and the ability of the sensor to recognize and respond to a Doppler shift
The second effect is the Doppler shift
factors 1/(1 [+ or -] v/c), giving the detected frequencies
The researcher said that they used the Doppler shift
for light to tell whether the gas in these quasars is moving away from Earth or toward these distant black holes, which have a mass from millions to billions of times that of the Sun.
Doppler Weather Radar measures not only the location and intensity of precipitation but also the wind speed and direction around radar sensors by analyzing the Doppler shift
of radio waves returned from precipitation particles in the wind.
He outlines the basics of Fourier analysis, radar fundamentals, and synthetic aperture radar; basic ISAR concepts; procedures for conventional ISAR imaging; imaging techniques and fine-tuning procedures such as zero-padding and windowing that enhance image quality; ISAR waveforms and receivers, quadrature detection, Doppler shift
phenomena, and range-Doppler ISAR imaging algorithms; scattering center representation of ISAR, including algorithms to reconstruct high-fidelity images and field data from the scattering centers; applications of ISAR to solve engineering problems such as antenna scattering and coupling; and motion compensation techniques, including the cross-correlation method, minimum entropy method, and joint-time, frequency-based motion compensation.
The major sources of uncertainty in frequency biases in thermal-beam, cesium frequency standards are second-order Zeeman shift, second-order Doppler shift
, end-to-end cavity phase shift and possibly cavity pulling, fluorescence light shift, and line-overlap shift.
Implications will be presented with emphasis on time dilation and the Doppler shift
as practical considerations.
The discovery of the quantum detection of gravitational waves, showing correlations between well separated locations, that permitted the absolute determination of the 3-space velocity of some 500 km/s, in agreement with the speed and direction from a number of previous analyses, including in particular the NASA spacecraft Earth-flyby Doppler shift
When a distress beacon is detected, its location can be computed based on the Doppler shift
of the beacon signal as the satellite passes overhead.
As a result of the Doppler shift
the spaceship would be bombarded by intense X-rays, exerting a pressure strong enough to slow it down.
HARPS finds distant worlds by focusing on wobbly stars pulled in different directions by orbiting bodies, causing a Doppler shift
in the color of the starlight.
