[PP2-3-8-2] Local Incidence Angle

The local incidence angle is the angle between the incident radar wave and the normal to the scattering surface at target location. In case of a flat terrain, the local incidence angle equals the incidence angle. For a terrain with local slope, the local incidence angle differs from the incidence angle (for slopes facing towards the sensor, it is smaller than the incidence angle).
