public class GroundPlaneSquintAngle extends Angle_90
From a collection perspective the squint angle may be expressed as the Doppler cone angle between the ground track vector and the radar’s line-of-sight vector or as a ground squint angle, which is the corresponding angle projected onto the ground plane. Here, the ground plane is the geodetic plane orthogonal to the ellipsoid normal at the SRP, although it may also be defined as the geocentric plane. Most often, the squint angle is defined relative to the sensor velocity vector. However, it is technically defined as the ground-track angle to which the SAR imagery is formed. It can be interpreted as the average velocity vector along the synthetic aperture, or approximated from a single velocity measurement at some position in the aperture, typically the SRP, barring the availability of the ground-track angle.
For the ground plane squint angle, forward of broadside is positive and aft of broadside is negative.
