    Instrument description of the airborne microwave temperature profiler (1989)
    In:  Other Sources
    Details
    Publikationsdatum: 2011-08-19
    Beschreibung: The microwave temperature profiler (MTP) is a passive microwave radiometer installed in the NASA ER-2 aircraft and used to measure profiles of air temperature versus altitude. It operates at 57.3 and 58.8 GHz, where oxygen molecules emit thermal radiation. Brightness temperature is measured at a selection of viewing elevation angles every 14 s. MTP was the only remote sensing experiment aboard the ER-2 during the Airborne Antarctic Ozone Experiment. This paper describes hardware, calibration, and performance aspects of the MTP.

    Miniature modular microwave end-to-end receiver (1993)
    In:  CASI
    Details
    Publikationsdatum: 2019-06-28
    Beschreibung: An end-to-end microwave receiver system contained in a single miniature hybrid package mounted on a single heatsink is presented. It includes an input end connected to a microwave receiver antenna and an output end which produces a digital count proportional to the amplitude of a signal of a selected microwave frequency band received at the antenna and corresponding to one of the water vapor absorption lines near frequencies of 20 GHz or 30 GHz. The hybrid package is on the order of several centimeters in length and a few centimeters in height and width. The package includes an L-shaped carrier having a base surface, a vertical wall extending up from the base surface and forming a corner therewith, and connection pins extending through the vertical wall. Modular blocks rest on the base surface against the vertical wall and support microwave monolithic integrated circuits on top surfaces thereof connected to the external connection pins. The modular blocks lie end-to-end on the base surface so as to be modularly removable by sliding along the base surface beneath the external connection pins away from the vertical wall.

    Designing an infrared system to map and detect wildland fires (1989)
    In:  Other Sources
    Details
    Publikationsdatum: 2019-07-13
    Beschreibung: The 'Firefly' project is developing an infrared remote sensing system to provide near real-time wildland fire information for fire management and suppression. Recent technological advances in several areas now allow the design of an end-to-end, infrared system to map and detect wildland fires. The system components will include an airborne infrared sensor, automatic onboard signal and data processing, telecommunications link, and integration into a ground data terminal. The system will provide improved performance over current systems in terms of increased timeliness of data delivery, quantifiable accuracy, data consistency, reliability, and maintainability. The system will be the next generation of wildland fire mapping and detection system for the United States Forest Service.

    MMIC Receiver For Water-Vapor Radiometer (1993)
    In:  Other Sources
    Details
    Publikationsdatum: 2019-07-12
    Beschreibung: MMIC receiver puts out signal, frequency of which proportioned to brightness temperature of sky at input frequency of 31 GHz. Miniaturization enhances thermal stability and stability of calibration of water-vapor radiometer. Potential for mass production at relatively low cost. Facilitating widespread use of MMIC water vapor radiometers in meteorology and aviation, deployed at several global sites to improve capability of general circulation models and at airports to monitor icing conditions by measuring supercooled liquid water in clouds.

    Mapping Wildfires In Nearly Real Time (1993)
    In:  Other Sources
    Details
    Publikationsdatum: 2019-07-12
    Beschreibung: Airborne infrared-sensing system flies over wildfire as infrared detector in system and navigation subsystem generate data transmitted to firefighters' camp. There, data plotted in form of map of fire, including approximate variations of temperature. System, called Firefly, reveals position of fires and approximate thermal intensities of regions within fires. Firefighters use information to manage and suppress fires. Used for other purposes with minor modifications, such as to spot losses of heat in urban areas and to map disease and pest infestation in vegetation.
