The Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) instrument is a pod-based L-band polarimetric syntheic aperture radar (SAR) that acquires airborne repeat track SAR data for differential interferometric measurements. This effort takes two existing UAVSAR pods and installs them on the Global Hawk Unmanned Airpborne Vehicle (UAV) to enable long duration/long range data campaigns. This implementation of UAVSAR enables the generation of precision topographic maps and single pass polarimetric-interferometry (SPI) providing vertical structure of ice and vegetation. Global Hawk's range of ~9000 nm enables regional surveys with far fewer sorties as well as measurements of remote locations without the need for long complicated deployments.
JPL will be responsible for interfacing the exisiting UAVSAR pods to the airframe and modify radar control and timing to synchronize the two radar pods. JPL will develop ground data processing software necessary to onterpret the Single Pass interferometric data. JPL will participate in flight and ground testing and perform data analysis. The significant delervibles are: Perform a Preliminary Design Review, Critical Design Review, Instrument modification and laboratory testing and integration with the GH Platform.
