AB  - C-band microwave backscattering coefficient: the test site is reed land and corn land in Linze grassland intensive observation area. Main observation instruments: C-band ground-based microwave scatterometer, C-5, ls-c-5 (2) S-band ground-based microwave scatterometer, S-3, ls-s-3 (3) TDR soil moisture meter, instrument number, tdr-200.Main observation contents: vegetation data measured in July and August 2008 (synchronized with ASAR at about 11:30 noon), polarization mode: VV polarization, HH level, bare soil, VH cross polarization. Measure soil moisture.Vegetation data were measured on July 9, 2008. Polarization methods: HH polarization, HV polarization, VV polarization and VH polarization. Soil moisture of grassland was measured. July 10, 2008 - measure the horizontal (the front end of the corn field is horizontal and the rear section is vertical) corn field, and the polarization modes are VV polarization, HH polarization, VH polarization and HV polarization. Measure soil moisture in corn fields. On July 11, 2008, the grassland was measured (measured synchronously with ASAR at about 11:30 noon). The measurement direction was north-south, and it was East-West before. From 7:30 a.m., the air humidity is high, and the dew of the grassland is also large - the difference in time can lead to the difference of the same measurement data at different times. You can refer to the variation law of air humidity, soil moisture and dew in this area. Polarization mode: VH, HH, VV, HV. It mainly measures grassland humidity. See the measurement data description document in the document for detailed observation
