A method of detecting distant objects and determining their position, velocity, or other characteristics by analysis of sent radio waves (usually microwaves) reflected from their surfaces
Radio Detecting and Ranging; a device which transmits a microwave pulse, and calculates the distance, direction, and speed of an object from the returned pulse reflected by the object
an electronic instrument that broadcasts and receives microwave signals back from precipitation areas, and determines their location, height, movement, and intensity rainbow: an arc displaying all colors in the visible light spectrum Formed when light from the sun is reflected and refracted through water droplets Always appears on the side of the sky opposite of the sun reflectivity: a measure of how well a surface turns the part of the radiation it receives back in the direction from which the radiation came refraction: bending of light as it passes through something with different properties, such as a light beam bending as it travels through glass relative humidity: ratio of the actual vapor pressure of the air to the saturation vapor pressure for the surrounding air temperature In other words, how much water the air is holding divided by how much water the air is capable of holding
radio detecting and ranging; a device used to detect and determine the range to distant objects (e g , hydrometeors) or atmospheric discontinuities by measuring the time for the echo of a radio wave to return from it and the direction from which it returns
Radar is a way of discovering the position or speed of objects such as aircraft or ships when they cannot be seen, by using radio signals. a piece of equipment that uses radio waves to find the position of things and watch their movement sonar (radio detection and ranging). System that uses electromagnetic echoes to detect and locate objects. It can also measure precisely the distance (range) to an object and the speed at which the object is moving toward or away from the observing unit. Radar (the name is derived from radio detecting and ranging) originated in the experimental work of Heinrich Hertz in the late 1880s. During World War II British and U.S. researchers developed a high-powered microwave radar system for military use. Radar is used today in identification and monitoring of artificial satellites in Earth orbit, as a navigational aid for airplanes and marine vessels, for air traffic control around major airports, for monitoring local weather systems, and for spotting "speeders
By emitting high frequency radio waves and measuring where and how fast they were reflected, a radar instrument can measure things like distance, direction, speed, etc A radar instrument can "see" objects in the dark as well as penetrate cloud cover
Acronym for RAdio Detection And Ranging An electronic instrument used to detect distant objects and measure their range by how they scatter or reflect radio energy Precipitation and clouds are detected by measuring the strength of the electromagnetic signal reflected back
Term coined from the phrase "Radio Detecting and Ranging " It is based on the principle that ultra-high frequency radio waves travel at a precise speed and are reflected from objects they strike It is used to determine an object's direction and distance
An instrument for determining the distance and direction to an object by measuring the time needed for radio signals to travel from the instrument to the object and back, and by measuring the angle through which the instrument’s antenna has traveled
An acronym for radio range and detecting A radio detection device that uses pulses of microwave-length energy to provide range, azimuth, and/or elevation data of objects
A device that detects distant objects and determines their position, velocity, and other characteristics by analysis of very high frequency radio waves reflected from their surfaces Since the introduction of radar during the Second World War, radar countermeasures have been under development as well, and stealth technology is now an effective means of avoiding detection See also stealth technology
The technique of transmitting radio waves to an object and then detecting the radiation that the object reflects back to the transmitter; used to measure the distance to, and motion of, a target object
A system or device which uses transmitted and reflected radio waves to detect objects, along with their direction, distance, height, and speed in relation to the device
Radyo dalgalarının yankısını alarak cisimlerin yerini ve uzaklığını bulabilen, genellikle uçak ve gemilerde kullanılan cihaz. İçgüdü, seziş: "... büyük yurt sevgisinin yüce boyutlarını analık radarı ile pek iyi sezebilmektedir."- H. Taner
