Because the external radar causing the transponder to respond is generally not synchronised with your own radar (i.e. different pulse-repetition frequencies), these black dots appear randomly across the display and the operator sees through and around them. The returning image may be much larger than the "dot" or "hole", as it has become known ...
The RR-144 is designed to prevent interference with civil ATC radar systems. Chaff, originally called Window [1] or Düppel, is a radar countermeasure involving the dispersal of thin strips of aluminium, metallized glass fiber, or plastic. [2] Dispersed chaff produces a large radar cross section intended to blind or disrupt radar systems. [3]
A radar detector is an electronic device used by motorists to detect if their speed is being monitored by police or law enforcement using a radar gun. Most radar detectors are used so the driver can reduce the car's speed before being ticketed for speeding .
Princeton university engineers have created a type of Doppler radar, typically used to catch speeding cars, that bounces radio waves off stationary objects to effectively “see” around corners.
The hardware includes eight cameras covering an aggregate view of 360° around the car and 12 ultrasonic sensors, in addition to forward-facing radar with enhanced processing capabilities. [22] The radar is able to observe beneath and ahead of the vehicle in front of the Tesla; [ 23 ] the radar can see vehicles through heavy rain, fog or dust ...
General Motors Co's venture capital arm has invested millions of dollars in Oculii, a U.S. startup maker of software for radar sensors used in self-driving cars, Oculii co-founder Steven Hong said.
Electronic stability control (also known as roll over protection) is a specific technology that helps keep the vehicle balanced. During harsh weather or tough road conditions that would cause vehicle steering to be extreme, this technology allows the drivers to regain control and prevent possible crashes, roll overs, and fishtails.
Search radar that include pulse-Doppler are usually dual mode because best overall performance is achieved when pulse-Doppler is used for areas with high false alarm rates (horizon or below and weather), while conventional radar will scan faster in free-space where false alarm rate is low (above horizon with clear skies).
