radar astronomy

While the facility soon evolved to become the third largest radio observatory in the world, some radar astronomy continued.

His specialty areas are radio astronomy and radar astronomy.

His research interests include radar imaging, optical signal processing, and radar astronomy.

Radar astronomy differs from radio astronomy in that the latter is a passive observation and the former an active one.

In fact, essentially all major radar astronomy activities have been conducted as adjuncts to radio astronomy observatories.

Project Diana marked the birth of the US space program, as well as that of radar astronomy.

In this radar astronomy procedure radio waves of known wavelength are emitted from a radio telescope aimed at an asteroid.

Much of Dr. Ostro's career focused on the development of asteroid radar astronomy.

Radar astronomy is a technique of observing nearby astronomical objects by reflecting microwaves off target objects and analyzing the echoes.

It also performs radio and radar astronomy observations for the exploration of the solar system and the universe, and supports selected Earth-orbiting missions.

Pulse-Doppler radar is also the basis of synthetic aperture radar used in radar astronomy, remote sensing and mapping.

Steven Jeffrey Ostro (March 9, 1946 - December 15, 2008) was an American scientist specializing in radar astronomy.

He works on radar astronomy devices, near-Earth asteroid radar research, and SETI.

His experiments with microwaves reflected from the Moon in 1946 helped start radar astronomy, in which celestial bodies are studied by bouncing radio signals off their surfaces.

It is used in three major areas of research: radio astronomy, aeronomy, and radar astronomy observations of the larger objects of the Solar System.

The first definite proof that a signal could be sent to Venus and returned to Earth, using radar astronomy, was made by the Jet Propulsion Laboratory.

He was the driving force behind using the then-new Millstone radar at the MIT Lincoln Laboratory for the earliest work in radar astronomy.

Sea-based radar systems, semi-active radar homing, weather radar, military aircraft, and radar astronomy rely on the Doppler effect to enhance performance.

John H. DeWitt, Jr. (February 20, 1906 - January 25, 1999) was an American pioneer in radio broadcasting, radar astronomy and photometry.

Owned by the U.S. National Science Foundation and contractor operated, it is used primarily for radio astronomy, but equipment is available for radar astronomy.

The Jodrell Bank Observatory, an operation of the University of Manchester in Great Britain, was originally started by Bernard Lovell to be a radar astronomy facility.

The Lunar Laser Ranging Experiment, radar astronomy and the Deep Space Network determine distances to the Moon, planets and spacecraft, respectively, by measuring round-trip transit times.

A number of radio observatories were constructed during the following years; however, because of the additional cost and complexity of involving transmitters and associated receiving equipment, very few were dedicated to radar astronomy.

Vladimir Aleksandrovich Kotelnikov - information theory and radar astronomy pioneer, mostly known for having discovered, independently of others (e.g. Edmund Whittaker, Harry Nyquist, Claude Shannon), the sampling theorem in 1933.
