Question

The part radiation due to scattered diffused radiation entering the field of view of a remote sensor other than that from the required target

• A. \( \text{Increases the contrast of the image but reduces the sharpness} \)
• B. \( \text{Reduces the contrast of the image and also its sharpness} \)
• C. \( \text{Increases both the contrast and sharpness} \)
• D. \( \text{Reduces the contrast but increases the sharpness} \)

Hint:

Think of atmospheric scattering like fog or haze that obscures the clear view of the ground.

Answer 1

The Correct Option is B

The scattered, diffused radiation that enters the remote sensor's field of view without originating directly from the intended target is known as atmospheric scattering or path radiance. This unwanted radiation adds a hazy veil to the image, reducing both the contrast (by brightening darker areas and dimming brighter areas) and sharpness (by blurring fine details) of the image.
