Radar and simple range problem

  1. Dec 4, 2016 #1
    1. The problem statement, all variables and given/known data
    Radar (radio wave) is placed 35m above sea level. Calculate working range of radar.

    2. Relevant 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.
    3. The attempt at a solution
    There should be some kind of simple approximate formula. Can someone help?

    Not enough information to give even a ball park answer .

    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 .

    My computer declares that site to be dangerous and says I should not access it under any circumstances.

    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 .
