active sensor meaning

• [Electronics]
  In an electronic security system, a transducer that generates an electromagnetic field or acoustic-wave field, and detects changes in the field resulting from the presence or movement of objects in the vicinity.
  

• Active sensors had blue connectors and Passive sensors had yellow connectors.
• In regard to sensors, airborne sensor operators work with either active sensors or passive sensors.
• CMOS chips, by contrast, consist of active sensors that have tiny transistors as power sources.
• The system includes a 3D active sensor, a thermal imager and Neptec's model based tracking software.
• Sensors may be passive or coupled to an active source ( i . e ., " active sensor " ).
• Sensors are classified into three categories : passive, omnidirectional sensors; passive, narrow-beam sensors; and active sensors.
• Active sensors actively probe the environment, for example, a sonar or radar sensor, and they require continuous energy from a power source.
• The other application is to serve as a self-powered active sensor, because it does not need an external power source to drive.
• The typical active sensors used by sensor operators are Synthetic Aperture Radar ( SAR ), Light Detection and Ranging ( LIDAR ) and sonar.
• If the player has selected the EMCON option, none of his units start the game with active sensors on; only passive sensors will be engaged.

• "active sensor" meaning in Chinese: 有源传感器
• "active sensor" meaning in Japanese: 能動的｛のうどうてき｝センサー
