Micropower impulse radar is a low-power ultra wideband radar developed in the mid-1990s〔Science & Technology Review January/February 1996 https://www.llnl.gov/str/pdfs/01_96.2.pdf〕 at Lawrence Livermore National Laboratory, used for sensing and measuring distances to objects in proximity to each other. Commercial applications include: *Vehicles: parking assistance, backup warnings, precollision detection and smart cruise control (measures the distance to the vehicles in front of you and if they get too close, throttle is released and brakes are applied). *Appliances: studfinders and laser tape measures. *Security: home intrusion motion sensors and perimeter surveillance. *Search and rescue: micropower impulse radar can detect the beating of a human heart or respiration from long distances. ==External links== * *(【引用サイトリンク】title=Micropower Impulse Radar (MIR) ) 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Micropower impulse radar」の詳細全文を読む スポンサード リンク
