Leaf Area Index Inversion Based on Ground Passive Microwave Measurement Experiment
The passive microwave sensor can provide significant information compared with optical and infrared sensors due to its penetrating property.It plays an important role in the detection of growth vigour of corps.In this paper,consecutive passive microwave detection experiments were conducted considering row direction effect.The result showed that a well negative exponential relationship exists between normalized MPDI and LAI for frequencies 6.6 and 18.7 GHz.With the increase of measurement angle,the negative exponential relationship is more obvious.When observation is parallel to the row,two MPDIs at 6.6 and 18.7 GHz at same observation angle have a good linear relationship,but when observation is vertical to the row or cross 45° with the row the linear relationship becomes weak.
