microwave radar
Noun: A system or device that uses the reflection of short-wavelength radio waves (microwaves) to determine the range, angle, or velocity of objects. It is a technology for detecting the presence, direction, distance, and speed of aircraft, ships, weather formations, and other objects by sending out pulses of high-frequency electromagnetic waves and analyzing the reflected signals.
"Microwave radar" is a technical term. It functions as a compound noun, typically used as the subject or object in a sentence to describe the technology or a specific instance of its use. * The airport's security relies on advanced microwave radar to monitor air traffic. * Scientists installed microwave radar to study the movement of glaciers.
- Modern weather forecasting depends heavily on data from microwave radar systems.
- The naval vessel's microwave radar detected the small boat several miles away.
- This research paper compares the effectiveness of optical sensors versus microwave radar for autonomous vehicles.
The term is often used in technical, military, scientific, and engineering contexts. It can be specified further: * Synthetic Aperture Radar (SAR): A form of microwave radar used to create detailed two-dimensional images or three-dimensional reconstructions of landscapes. * Pulse-Doppler radar: A specific microwave radar system that uses the Doppler effect to measure target velocity.
- Radar: The more common and general short form for "radio detection and ranging," which encompasses microwave radar.
- RADAR: An acronym for "Radio Detection And Ranging."
- Ranging: The process of determining the distance to a target.
- Echo: The reflected signal detected by the radar receiver.
- RADAR
- Radar system
- Detection system
- Ranging device
- Radar cross-section: A measure of how detectable an object is by radar.
- Radar echo: The reflected signal returned to the radar receiver.
- Radar sweep: The movement of a radar beam as it scans an area.
"Microwave radar" explicitly specifies the portion of the radio frequency spectrum used, distinguishing it from other types of radar (e.g., millimeter-wave radar). In everyday language, the word "radar" alone is almost always understood to mean microwave radar.
- measuring instrument in which the echo of a pulse of microwave radiation is used to detect and locate distant objects
