Quantification of Above Ground Biomass (AGB) across oil palm plantation is essential for wide range of modern-day research and management demands。 Information on the spatial distribution of Oil Palm Plantation AGB is therefore important for the Oil Palm industry。 In this study， the oil palm plantation in Perak， Malaysia was accessed to obtain the AGB information。 The lack of information on biomass due to the uncertainties and cost has limited its availability over the years。 This research investigates the determination of AGB of oil palm plantation。 Phased Array type L-band Synthetic Aperture Radar (PALSAR) sensor is an added advantage to overcome the cloud problem to analyze the biomass of the oil palm plantation， particularly in cloud covered tropical regions。 Ground data of oil palm biomass which covers palms of ages 6，8，10 and 12 years old are compared to the estimation of AGB by PALSAR for all the polarizations。 PALSAR images were applied various filters and compared among the four window sizes of 3×3， 5×5， 7×7，and 9×9。 The filters used in this study are Gaussian low， Gaussian high， Laplacian and Median filter that was applied in VV polarized image。 Speckle suppression index was applied to allow checking of filters' efficiency and thus selection of model building。 The resulting model constructed from this study showed a R~2 regression of 0。90 with the VV polarization between the field data results and filtered PALSAR data of biomass。
