Question

if we increase the altitude of an imaging system with constant FOV, spatial resolution will
a) very coarse
b) very fine
c) decrease
d) increase​

Answer 1

hello friend

Explanation:

The resolution will a increase

Answer 2

Answer:

The correct answer is c, i.e., spatial resolution will decrease when the altitude of an imagining system with constant FOV increases.

Explanation:

The smallest object that the sensor can resolve, the area of the ground that was imaged for the sensor's instantaneous field of view (IFOV), or the linear dimension on the ground that is represented by each pixel are all terms that describe spatial resolution.

When FOV is constant then the spatial resolution inversely depends on the altitude. Higher the altitude, lesser the spatial resolution and vice versa. Therefore, if altitude increases then the spatial resolution will decrease and the image will become less clearer.

Hence, the correct answer is c.
