Satellites

dynamic range

Aerospace; Satellites

the range between the maximum and minimum amount of input radiant energy that an instrument can measure.

signal

Aerospace; Satellites

The effect (for example, a pulse of electromagnetic energy) conveyed over a communications path or system. Aboard Landsat, signals from the scene being sensed are received by the sensors and ...

radiance-based calibration

Aerospace; Satellites

The empirical calibration of satellite sensors by measurement of upwelling radiation from targets that are viewed on the ground or from aircraft at the same time as from space. The at-satellite ...

sidelap

Aerospace; Satellites

The extent of lateral overlap between images acquired over adjacent ground tracks. Sidelap increases with distance from the equator.

The field calibration of satellite sensors by measurement of reflected solar radiation from targets of known or measured reflectance that are viewed on the ground at the same time as from space. The ...

modulation transfer function (MTF)

Aerospace; Satellites

The geometric description of a detector’s instantaneous field-of-view (IFOV) from the satellite. The modulation transfer function (MTF) is a frequency-based characterization of the IFOV of the plane ...
