Measurements and Applications
|
A multiple channel radiation imager, one of the primary instruments aboard FY-4. Technically featured by a precisely designed two-mirror structure, capable of accurate and flexible sensing in two dimensions, and minute-level fast sector scanning. Frequent Earth imaging over 14 bands with off-axis three reflections of the primary optic system. On-board black body available for IR calibrations at very short time intervals.
