what type of electromagnetic waves are used in radar?
9056
The waves used in the radar are radio waves or microwaves,where the radar is usualy used to detect and track space objects and ballistic missiles,this is a long range radar antena.

Radio waves, television waves, and microwaves are all types of electromagnetic waves.

Microwaves can be measured in centimeters. They are good for transmitting information because the energy can go through substances such as clouds and light rain. Short microwaves are sometimes used in Doppler radars to predict weather forecasts. Infrared radiation can be released as heat or thermal energy.

Parts of the radio spectrum are used for radar and passive detection. Above the radio-frequency spectrum lies the infrared spectrum, followed by the visible range, which is quite narrow.

Radio waves, television waves, and microwaves are all types of electromagnetic waves. They only differ from each other in wavelength. ... Waves in the electromagnetic spectrum vary in size from very long radio waves the size of buildings, to very short gamma-rays smaller than the size of the nucleus of an atom.

Electromagnetic radiation is used for communications and transmission of information. The waves that are used in this way are radio waves, microwaves, infrared radiation and light. The idea of using a signal lamp to communicate was used in the 19th century.

Military Radar systems work in a wide band of transmitted frequencies. The higher the frequency of a radar system, the more it is affected by weather conditions such as rain or clouds. But the higher the transmitted frequency, the better is the accuracy of the radar system.

The marine radar is classified under the x-band (10 GHz) or S-band (3GHz) frequencies. The x-band, being of higher frequency is used for a sharper image and better resolution whereas the S-band is used especially when in rain or fog as well as for identification and tracking.

Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. ... Naturally occurring radio waves are emitted by lightning and astronomical objects. Radio waves are generated artificially by transmitters and received by radio receivers, using antennas.
3641
Radio wave, wave from the portion of the electromagnetic spectrum at lower frequencies than microwaves. ... They are used in standard broadcast radio and television, shortwave radio, navigation and air-traffic control, cellular telephony, and even remote-controlled toys.
648715
They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications. The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz.
1343679
Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. ... Like all other electromagnetic waves, radio waves travel at the speed of light in vacuum.

Characteristics of electromagnetic waves Electromagnetic waves are transverse waves, similar to water waves in the ocean or the waves seen on a guitar string. This is as opposed to the compression waves of sound. As you learned in Wave Motion, all waves have amplitude, wavelength, velocity and frequency.

Radar is an acronym for "radio detection and ranging." A radar system usually operates in the ultra-high-frequency (UHF) or microwave part of the radio-frequency (RF) spectrum, and is used to detect the position and/or movement of objects. ... Radar can also render precise maps.

11.3 Electromagnetic spectrum (ESADK) EM radiation is classified into types according to the frequency of the wave: these types include, in order of increasing frequency, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

Introduction. A 3D radar measures 3D position (range, azimuth, elevation angle and possibly range rate). A 2D radar measures 2D position (range, azimuth and possibly range rate.) (with range and range rate, but no elevation information).

Radio waves can be generated by natural sources such as lightning or astronomical phenomena; or by artificial sources such as broadcast radio towers, cell phones, satellites and radar. AM radio waves are used to carry commercial radio signals in the frequency range from 540 to 1600 kHz.
