Using GPS reflections for satellite remote sensing [PDF]
Acta Astronautica, 2004 GPS signals that have reflected off of the ocean's surface have shown potential for use in oceanographic and atmospheric studies. The research described here investigates the possible deployment of a GPS reflection receiver onboard a remote sensing satellite in low Earth orbit (LEO).

Remotely sensing the photochemical reflectance index, PRI [PDF]
SPIE Proceedings, 2015 In remote sensing, the Photochemical Reflectance Index (PRI) provides insight into physiological processes occurring inside leaves in a plant stand. Developed by 1,2 , PRI evolved from laboratory reflectance measurements of individual leaves. Yet in a remotely sensed image, a pixel measurement may include light from both reflecting and transmitting ...

Analysing and correcting the differences between multi-source and multi-scale spatial remote sensing observations. [PDF]
PLoS ONE, 2014 Differences exist among analysis results of agriculture monitoring and crop production based on remote sensing observations, which are obtained at different spatial scales from multiple remote sensors in same time period, and processed by same algorithms,

Calibration methodology for mapping within-field crop variability using remote sensing [PDF]
, 2003 A successful method of mapping within-field crop variability of shoot populations in wheat (Triticum aestivum) and barley (Hordeum vulgare L.) is demonstrated. The approach is extended to include a measure of green area index (GAI). These crop parameters
