% Compute the intersection curve between a sensor cone and spherical planet.
If no outputs are given this will generate a 3D plot of the sensor
field of view. The nadir axis is drawn in green and the sensor
boresight in yellow. This function has a built-in demo.
Since version 8.

Form:
d = RapidSwath( lat, lon, h, halfAngleFOV, pitch, azimuth, Rp );
--------------------------------------------------------------------------
------
Inputs
------
lat (1,1) Latitude of satellite (rad)
lon (1,1) Longitude of satellite (rad)
h (1,1) Altitude of satellite (km)
halfAngleFOV (1,1) Sensor cone half-angle field of view (rad)
Note: 0 <= halfAngleFOV <= PI/2
pitch (1,1) Pitch angle between boresight axis and nadir axis (rad)
Note: 0 <= pitch <= PI
azimuth (1,1) Azimuth angle from north (rad)
Rp (1,1) Planet radius. Optional. Default is Earth radius. (km)
-------
Outputs
-------
d (.) Data structure with fields:
.r Set of 3D position curves for each elevation
.lat Set of latitude vectors for each elevation
.lon Set of longitude vectors for each elevation
.intersect Flag indicating whether the cone intersects
the planet.
.aboveHorizon Flag indicating whether any part of the cone
goes above the horizon.
