Enter a value for some component of the baseline, and the program will show the expected interferometric phase image for that baseline, using a flat-Earth model.
The phase can be displayed in color or grey-scale, and shows an entire swath of several popular satellites. Black to white, or one color cycle, depicts phase varing from 0 to 360 degrees.
Note that reasonable values for the normal and parallel baseline components are between -150 and 150 meters. Reasonable delta (change in baseline across the scene) values are -3 to 3 meters. Since this program shows an entire swath, larger values may create bands that are spaced less than one pixel apart, creating a confusing aliased pattern.
