Frozen Ground Monitoring Using Palsar/alos Data
نویسندگان
چکیده
Microwave remote sensing has shown proof of its effectiveness for frozen ground mapping due to the high difference of permittivity between frozen and unfrozen soil. However, the characterization of seasonal frozen ground still remains a problematic application. The Japan Aerospace Exploration Agency (JAXA) launched the Advanced Land Observing Satellite (ALOS) on the 24 of January 2006. This satellite has the Phased Array type L-Band Synthetic Aperture Radar (PALSAR) allowing fully polarimetric data acquisition. Furthermore, ALOS initial calibration phase has been achieved, showing good results for polarimetric calibration. Consequently, frozen ground characterization using PALSAR sensor is investigated in this paper.

متن کاملEstimating Soil Moisture Distributions across Small Farm Fields with ALOS/PALSAR
The ALOS (advanced land observing satellite) has an active microwave sensor, PALSAR (phased array L-band synthetic aperture radar), which has a fine resolution of 6.5 m. Because of the fine resolution, PALSAR provides the possibility of estimating soil moisture distributions in small farmlands. Making such small-scale estimates has not been available with traditional satellite remote sensing te...
