| 講演名 | 2008-11-25 15:30 A Regression Model Based on Second Intensity Moment for Estimating Coniferous Tree Biomass from High-Resolution L-band Cross-Polarized Pi-SAR Data ○Haipeng Wang（Fudan Univ.）・Kazuo Ouchi（National Defense Academy）  SANE2008-79 |

| 抄録 | （和） | Results are described on the regression analysis between the coniferous tree biomass and the second intensity moment of the L-band high-resolution cross-polarized synthetic aperture radar (SAR) images. From the regression analysis, the moment-based model for estimating tree biomass was developed and its accuracy was tested. The SAR data were acquired by the airborne polarimetric interferometric SAR (Pi-SAR) developed jointly by the National Institute of Information and Communications Technology (NICT) and the Japan Aerospace Exploration Agency (JAXA) over the Tomakomai national forests in Hokkaido, Japan. The comparison of the tree biomass values estimated by the model function and those measured by the field survey showed the average measurement accuracy of 85% for individual forest stands, which is similar to the accuracy (86%) of the previous K-distribution model. The moment model is robust and does not require any specific probability density function (pdf) that fits to the image texture. |
