Answer 2

When the FOV is $49.5\textdegree$ and swath width is 650 km, the flying height will be equal to (b) 705 km.

Step-by-step Explanation

Given:

• The FOV is equal to $49.5\textdegree$.
• The swath width is equal to $650$ km.

To Find: To find the flying height in the given case when FOV and swath width are given.

Solution:

The formula for swath width is given by,

$W=2Htan(\theta/2)$, where W = swath width, H = flying height, and $\theta/2$ = one-half of the total field of view (FOV) of the scanner.

Now, substituting the given values in the formula for swath width, we get

$49.5=2Htan(49.5/2)\\\implies 49.5=2Htan(24.75)$

Rearranging the equation to find the flying height, we get

$2H=\frac{49,5}{tan(24.75)}\\ \implies H=\frac{49,5}{2 \times tan(24.75)}$

Solving, we get

$H=704.9794$ km

$\implies$ H=705 km (approx)

Therefore, the flying height is equal to (b) 705 km.
