A method to estimate biomass in forest has become a subject of special interest because the importance of forests in the Earth's carbon cycle has been increasingly recognized. We study a method to estimate a biomass with airborne synthetic aperture radar (SAR). Our airborne SAR provides dual-frequency (L- and X- bands), full polarimetric data with a high resolution of 1.5 m. Our test site is Tomakomai (42.43'N, 141.34'E), which is located in the northern part of Japan. The survey on the biophysical properties were conducted at the same period of flight experiment in July 1999. We describe the discrimination between spieces using polarimetric or mufti-temporal SAR data. Moreover we report the relation between biophysical properties and backscattering coefficient of SAR.
