- The word radar is an acronym derived from the words RAdio Detection And Ranging. It refers to the technique of using radio waves to detect the presence of objects in the atmosphere. Radar was designed shortly before World War II. Its primary purpose was to detect the presence of aircraft. Today, radar is used for a wide array of applications, but primarily to detect precipitation and other meteorological events.

How Radar Works The received signals are displayed on a display system. Radar output generally comes in two forms: reflectivity and velocity. Reflectivity is a measure of how much precipitation exists in a particular area. Velocity is a measure of the speed and direction of the precipitation toward or away from the radar.

Meteor Scatter obs with VHF Radio & Computer No HF or VHF radio emission emanating form the meteor or the trail can be found, only heat in the infra red region, but those are not radio wavelengths. I've been told: the ionized plasma trail of a meteor, or the ionization cone around the head of the meteor, is capable to reflect, or scatter, radio waves.

Radar detector Radar detectors use a superheterodyne receiver to detect these electromagnetic emissions from the radar gun, and raise an alarm to notify the motorist when a transmission is detected.

Microwave remote sensing The microwave energy recorded by a passive sensor can be emitted by the atmosphere (1), reflected from the surface (2), emitted from the surface (3), or transmitted from the subsurface (4). Because the wavelengths are so long, the energy available is quite small compared to optical wavelengths.

- Local Weather Radar Sites in South Dakota. Radar is an acronym that stands for RAdio Detection And Ranging. A weather radar consists of a parabolic dish (it looks like a satellite dish) encased in a protective dome and mounted on a tower of up to five stories tall. About 150 NEXRAD (NEXt generation of weather RADar) Doppler radars were installed throughout the U.S. in the 1990s. The radar itself does not delineate between rain and snow but AccuWeather's proprietary algorithms do, based on atmospheric conditions. The state-level Snow/Ice/Rain (Standard) radar images update every 5 minutes on AccuWeather.com Premium, which also gives access to longer loops of radar data.

Radar An airplane's radar is a bit like a torch that uses radio waves instead of light. The plane transmits an intermittent radar beam (so it sends a signal only part of the time) and, for the rest of the time, listens out for any reflections of that beam from nearby objects.

This Month in Physics History April, 1935: British Patent for Radar System for Air Defense Granted to Robert Watson-Watt. Many scientists and engineers contributed to the development of radar systems, which played a vital role in the Allied victory in WWII. Radar (the acronym stands for Radio Detection And Ranging), detects distant objects such as airplanes or ships by sending pulses of radio waves and measuring the reflected signal. One of the greatest radar pioneers was Sir Robert Watson-Watt, who developed the first practical radar system that helped defend the British in WWII. The basic principles needed for radar systems were established in the 1880s, when German physicist Heinrich Hertz first produced and transmitted radio waves across his laboratory.

WHAT YOU SHOULD KNOW ABOUT RADAR AND RADAR DETECTORS AND RADAR DETECTORS. How Traffic Radar Works. Traffic radar uses a radar beam to measure speed. Think of the beam as a searchlight. It’s invisible because it’s made of microwaves instead of light, but otherwise it acts very much like a light beam. It travels in straight lines.

Radar A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the object(s).

Radar Another example of the extremes encountered in a radar system is the timing. An air-surveillance radar (one that is used to search for aircraft) might scan its antenna 360 degrees in azimuth in a few seconds, but the pulse width might be about one microsecond in duration. Some radar pulse widths are even of nanosecond (10−9 second) duration.

Radical behaviorism Radical behaviorism inherits from behaviorism the position that the science of behavior is a natural science, a belief that animal behavior can be studied profitably and compared with human behavior, a strong emphasis on the environment as cause of behavior, and a penchant for operationalizing.adical behaviorism as a natural science [edit]. The most precise way to describe radical behaviorism as radical is to understand that instances such as evolution and cell division are occurrences that just happen.

Ground Penetrating Radar Services Nationwide Ground penetrating radar operates by transmitting pulses of ultra high frequency radio waves (microwave electromagnetic energy) down into the ground through a transducer (also called an antenna). The ground penetrating radar antenna (transducer) is pulled along the ground by hand or behind an ATV or a vehicle.

- Rain attenuation has a relate directly to transmitted frequency, the higher the frequency, the bigger rain attenuation is. Since on the customer side (downlink from the satellite) the antenna dish diameter is low (typically 60 to 100 cm), and since antenna gain is a function of the diameter, its susceptible to rain attenuation. This is why heavy rain jam your reception.

- Radio waves are reflected by many solid objects, such as wood, stone, and notably metal, allowing the use of microwaves in radar applications. Also importantly in broadcast radio, the ionosphere (an upper layer of the Earth's atmosphere) can bounce signals back down to locations beyond the line-of-sight horizon. 3 people found this useful.
