The Study on Decomposing AVHRR Mixed Pixels by Means of Neural Network Model
应用神经网络模型分解AVHRR混合像元

In large area crops yield estimation from remote sensing data, crops planting area estimation with NOAA data remains to be resolved difficultly. Those mixed pixed decomposition methods given before are impractiable, or not suitable for AVHRR data. In view of points above, a new method, more scientific and economic than before, is put forward, that is to estimate crops planting area by means of AVHRR mixed pixel neural network decomposition model, which comprehensively makes use of the advantages of both TM data and NOAA data .
