Image correction and preliminary analysis of a field measurement by a C-band airborne microwave synthetic aperture radiometer

Image correction and preliminary analysis of a field measurement by a C band 6-channel airborne microwave synthetic aperture radiometer is presented. This measurement was carried out along the Yellow River banks, Shaan´Xi, China, during 25^th to 30^th April, 2002. The CSSAR one dimensional C-band (6.6 GHz) 6-channel synthetic aperture radiometer was used as the airborne sensor. On board of the helicopter, a GPS receiver is also used to record the geographical positions of the flight pass. The scan was carried in over a square area across the experiment fields covering about 8×8 km². Ground truth observation also took place at the same time. The ground measurement parameters include: temperature of water body, air temperature, soil temperature, soil moisture at varied depth, soil surface roughness, etc. Geometric correction and registration were done before the analysis of the imagery. Some preliminary results are given.
