“instantaneous field of view”的概念、定义、翻译、参考文献-科学参考

instantaneous field of view

Space Exploration

An angular cone of visibility of a sensor on a spacecraft. For example, the IFOV for the advanced very high-resolution radiometer (AVHRR) carried on Polar-Orbiting Environmental Satellites (POEs) of the National Oceanic and Atmospheric Administration, is 1.4 milliradians. The IFOV determines the area of the Earth's surface scanned at any given time from a certain altitude. The area's size is found by multiplying the IFOV by the distance from the sensor to the Earth.

Geology and Earth Sciences

In remote sensing, the angle through which a detector is receiving electromagnetic radiation. It is often expressed as a function of the ground area visible at any one time, which is dependent on height and the angle of radiation reception.
