Any thoughts on these methods to monitor crop health ?

I’m trying to develop a method that can help in crop monitoring (grain crops like wheat and rice) using SAR. So far, I’ve narrowed it down to two methods and I don’t know if which path can lead to success.

  1. SAR dataset training: In this method, I’m planning to get an NDVI data set and train VH/VV data (from NRPB- normalized ratio procedure between bands) sentinel1. With regressions, a model is developed using a neural network. The true data set would be NDVI and the model will match this result taking SAR data input.

  2. Water cloud model: When I looked at the equation, it requires in-situ measurements. I don’t have the ground soil moisture data for the WCM equation. However, I can still computer the LAI from the sentinel 2 dataset. I have the ground precipitation and temperature data but those are not enough to get soil moisture.

as you don’t have moisture data from the field the first approach seems more robust.
The exact choice depends on what you exactly want to monitor: the type of crop or its condition.
