【正文】 Expected Completion Date: 3/30/2022 NonFederal Participants: Coherent Technologies, Lafayette, CO Project Description: This project will fabricate test, and demonstrate an eyesafe, multifunction coherent laser radar (ladar). The transceiver will support long pulse operations for wind field estimation, short pulse operation for hard target precision range and Doppler, and short doubletpulse (polypulse) operation for hardtarget vibration measurements. 58 ? Expected Military Application(s): This is a multifunction technology with broad military application. Expected military applications include: wind profiling for precision air drop and bomb drop, ground based wake vortex detection for increased flight safety, precision target range, Doppler and microDoppler target vibration signature estimation for long range target identification and targeting, airborne wake vortex measurement for air safety and precision delivery, terrain profiling, and target designation potential. 59 ? Expected Commercial Application(s): There are both mercial air and industrial/structural diagnostics applications. Expected mercial applications include: clear air turbulence detection for mercial flight safety, vertical wind profiling supporting flight safety and enhanced flight path fuel economy, groundbased wake vortex detection to assess runway hazards at high volume mercial airports, routine Pacific flight wind field estimation for CONUS weather prediction, helicopter landing area safety assessment, and remote vibration sensing for building/structural analysis. 。 NonFederal Contribution: $501,859。 53 Firepond “火池 ” 遠程 CO2成像激光雷達原理圖 54 ORACLE: Ozone Research with Advanced Cooperative Lidar Experiments NASA Canadian Space Agency Ti:sapphire and Nd:YLF。 300 km, 51 degrees or greater orbit MSFC/LaRC/JPL/GSFC/UAH/CTI/SWA Collaboration 51 SPARCLE Laser Transmitter 52 Firepond 單脈沖 CO2相干激光多普勒雷達 1975年美國 MIT林肯實驗室的路基 “ 火池 ” （ Firepond）單脈沖 CO2相干激光多普勒雷達，發(fā)射峰值功率為 15kW,平均功率為 ，重復(fù)頻率為 10kHZ,激光中心頻率為 3 1013Hz,探測器為 Ge摻 Cu。 45 Airborne wake vortex measurement 46 WindTracer MAG1 System 47 Wake Vortices Measurement at San Francisco International Airport 48 LD泵浦 Tm:Ho:YAG激光相干雷達系統(tǒng) 49 機載、星載測風(fēng)激光雷達 ? 1994, LITELidar InSpace Technology Experiment was successfully conducted aboard the space shuttle Discovery ?
