1. If the cross-track angular resolution of a satellite sensor at nadir is given by = 1.4 2/D where is the wavelength being observed and D is the aperture size of the sensor, what is the cross-track spatial resolution on the ground if D = 80 cm and the satellite sensor is at an orbital height of 600 km? (a) for an infrared sensor observing wavelengths at 20 microns? (b) for a microwave sensor observing wavelengths at 1.5 cm?
