“The incidence angle is defined as the angle between the vertical direction and the radar wave propagation vector at the surface (as shown in Fig. 1-3). When surface curvature effects are neglected, the look angle is equal to the incidence angle at the surface when the surface is flat.” Nothing to do with the North.

Hello periz,

Thanks for the detailed response.

When applying spatial filtering, in InSAR parameters, should be selected “Output Coherence = post-filtering”? So that this post-filtered Coherence was used on MISP module as Weights. I would appreciate it if you clarify this doubt.

Regarding AutoMISP-PRJ-Atmo.mat file, the image shows APS for 5 dates and three models. The same APS estimation (Full graph and linear model) was used on the three models, but the models differ on the MISP processing.
Model3 -> Full graph and liner model
Model5 -> Star graph and linear model
Model6 -> Star graph and Non-linear (Smart 5), not sure what 5 stand for?

My question is: Why Model 3 APS are different from Model 5 and 6? Note that I only estimated APS for model 3 and load the same APS in model 5 and 6.

Regards,
Arturo
