Radar systems must overcome unwanted signals in order to focus only on the actual targets of interest.

Radar jamming refers to radio frequency signals originating from sources outside the radar, transmitting in the radar's frequency and thereby masking targets of interest.

Radar video returns from aircraft can be subjected to a plot extraction process whereby spurious and interfering signals are discarded.

Radar was the most common form of SACLOS signals in early systems, because, in the anti-aircraft role the target is typically being " illuminated " by a radar signal anyway.

Radar signals passing near a massive object take slightly longer to travel to a target and longer to return than they would if the mass of the object were not present.

Pipe Penetrating Radar ( PPR ) is an application of GPR technologies applied in-pipe where the signals are directed through pipe and conduit walls to detect pipe wall thickness and voids behind the pipe walls.

Radar jamming and deception is the intentional emission of radio frequency signals to interfere with the operation of a radar by saturating its receiver with noise or false information.

The common types of remote sensing are Radar, Lidar, and satellites ( or photogrammetry ).

Radar and Lidar are not passive because both use EM radiation to illuminate a specific portion of the atmosphere.

Radar receivers are usually, but not always, in the same location as the transmitter.

Radar corner reflectors made of metal are used to reflect radio waves from radar sets.

Radar corner reflectors are designed to reflect the microwave radio waves emitted by radar sets back toward the radar antenna.

Radar altimeters are also a component of terrain avoidance warning systems, warning the pilot if the aircraft is flying too low, or if there is rising terrain ahead.

Two separate competing systems are currently operating within the US, Common ARTS ( Automated Radar Terminal System ( Lockheed Martin )) and STARS ( Raytheon ), with Common ARTS operating at the busiest facilities ( NY, Dallas, Atlanta, Southern California, Chicago, Washington DC area, Denver, St Louis, Minneapolis and San Francisco area ) within the US.

Radar energy is converted to heat rather than being reflected.

This has the effect that Radar will be incident at a large angle ( to the normal ray ) that will then bounce off at a similarly high reflected angle ; it is forward-scattered.

Providence, the state's capital, has a very strong local independent music scene, known especially for its contributions to the genre of noise rock, most notably the groups Lightning Bolt, Black Dice ( who later re-located to New York City ) and Arab on Radar.

Using the traditional radar technology at the time ( until the installation of NEXRAD Doppler Radar ) the storm had a well defined " hook echo " meaning the radar was picking up the wrapping of the rain around the circulation of the tornado.

Luggy ( Radar ) looked a lot like Cruncher, Snitch looked like Cruncher as well except Snitch wore orange, Brainy had no glasses and had no hair apart from around his ears and wore black, Blinky looked the same except he was bald and Alf and Fred had two hairs on their head and wore black and yellow.

: Every vessel must at all times maintain a proper look-out by sight ( day shape or lights by eyes or visual aids ) and hearing ( sound signal or Marine VHF radio ) as well as by all available means ( e. g., Radar, Automatic Radar Plotting Aid ( ARPA ), Automatic Identification System ( AIS ), GMDSS ...) in order to make a full assessment of the situation and risk of collision.
