echo intensity — The brightness or brilliance of a radar echo as displayed on an intensity indicated modulator. Echo intensity is, within certain limits, proportional to the voltage of the target signal or to the square root of its power. Bigger targets will have … Aviation dictionary
radar weather echo intensity levels — Radar weather echo intensity has been categorized into six levels of intensity for precipitation. They are weak, moderate, strong, very strong, intense, and extreme, corresponding to intensity levels 1 to 6, respectively … Aviation dictionary
Echo machine — An echo machine is the early name for a sound processing device used with electronic instruments to repeat the sound and produce a simulated echo. The device was popular with guitarists and was used by Jimmy Page and Syd Barrett among others.… … Wikipedia
echo box — An apparatus designed to test and calibrate a radar set. The transmitted pulse is fed into the echo box instead of the radar antenna. The echo box then produces a delayed return pulse, the intensity of which gradually falls at a certain rate.… … Aviation dictionary
Neutron spin echo — Science with Neutrons Foundations Neutron temperature Flux · Radiation … Wikipedia
Bow echo — A bow echo is a term describing the characteristic radar return from a mesoscale convective system that is shaped like an archer’s bow. These systems can produce severe straight line winds and occasionally tornadoes, causing major damage.… … Wikipedia
Reverse echo — or reverb, also known as backwards echo, is a slightly unusual sound effect created as the result of recording an echo or delayed signal of an audio recording whilst being played backwards. The original recording is then played forwards… … Wikipedia
Bounded weak echo region — Vertical cross section through a supercell showing the BWER. The bounded weak echo region, also known as a BWER or a vault, is a radar signature within a thunderstorm characterized by a local minimum in radar reflectivity at low levels which… … Wikipedia
Spin echo — In nuclear magnetic resonance, spin echo refers to the refocusing of precessing nuclear spin magnetisation by a 180° pulse of resonant radiofrequency.The NMR signal observed following an initial excitation pulse (orange in diagram) decays with… … Wikipedia
radar echo — i. The electromagnetic energy received after reflection from an object. Also called a radar return. See echo. ii. The deflection or change of intensity produced by a radar echo on a cathode ray tube display. It is a display of reflected radar… … Aviation dictionary
Animal echolocation — Echolocation, also called biosonar, is the biological sonar used by several animals such as dolphins, shrews, most bats, and most whales. The term was coined by Donald Griffin, who was the first to conclusively demonstrate its existence in bats.… … Wikipedia
