Description
A multi-spectral electronic self-scanning radiometer (MESSR) is an
electronic-scan-type radiometer which detects reflected solar rays from the
earth's surface in two visible bands and two near-infrared bands. It is
equipped with two camera systems that are parallel with the direction of flight
of the satellite. Each camera system is comprised of two optical units; one
for the visible range and the other for the near-infrared range. Each camera
system scans a width of 100 km of the earth surface at right angles to the
direction of flight of the satellite. When the two systems are used at the
same time, a width of 185 km can be scanned. Each has 2048 charge-coupled
devices (CCDs) for detection purposes, thus achieving a resolution of 50 m for
the earth's surface.
