Remote Sensing
7. A remote sensing satellite is operating at an altitude of 800 km. The
maximum nadir look angle of the scanning sensor is 30" side to side rel-
ative to the satellite's ground track. Calculate (a) the grazing angle and
(b) the slant range corresponding to the maximum look angle, and (c)
the total horizon-to-horizon FOV distance in km.
8. An active radar sensor sends a pulse of 3 x sec (3 nanosec) which
strikes the earth at a 30" incidence angle. Calculate the ground resolu-
tion in meters of the radar.
