How to Calculate the Working Range of a Radar Placed 35m Above Sea Level?

[prehisto]

Homework Statement

Radar (radio wave) is placed 35m above sea level. Calculate working range of radar.

Homework Equations

So I have found various different formulas for range but they all are very complicated with respect to my example. I only have 1 known variable - height.

The Attempt at a Solution

There should be some kind of simple approximate formula. Can someone help?

Have you some specific problem in mind ?

From my research on internet regarding this problem, I have the same opinion. But this example comes from school ( in topic elector magnetic waves) and therefore there should be some kind of simple answer.

With no other information available all you can say is that radar detection of a target is achievable anywhere between the transmitter site and the horizon .

That is for a simple line of sight radar system of sufficient power and a sea level target with good signal reflection characteristics .

Different answers for airborne targets and/or more sophisticated radar systems .

Just for interest : The radar horizon does not usually coincide exactly with the geometric horizon - radar horizon is usually further away - ie further around the Earth's curvature . How much depends on the sophistication of the radar system .

Both AVG Pro and Windows Defender passed it as ok . To be safe though I've removed the link .

The actual book is still available - though it is a bit expensive : Introduction to Radar Systems - Skolnik - McGraw-Hill .
