Workspace Method sensor_pos_losBackwardToAltitude

Description

Moves sensor_pos and sensor_los backwards to the target altitude.

The method gives the sensor_pos and sensor_los at the target altitude
to reach the original sensor_pos and sensor_los with a geometrical
ppath. That is, the movement is backwards in terms of viewing direction.

If the original sensor_los is reversed with respect to the line-of-sight
direction, then set the GIN los_reversed to 1. One such case is that
if sensor_los represents surface incidence angles, i.e. holds the
zenith and nadir angle towards the sensor.

There is also rte_pos_losBackwardToAltitude.
