Calculating beamwidth of a radar

[orla22]

beamwidth = 60(lamda) / area

i knw lamda = c x f

how do i find the area ? and also what is c and f in relation to radar?

 

[orla22]

i found c is speed of light and freq should be in question as for area, how do i find this

To find the area in this equation, you would need to know the physical dimensions of the radar antenna. This could include the diameter or length of the antenna. The area would be calculated using the appropriate formula for the shape of the antenna, such as A = πr^2 for a circular antenna.

In this equation, c refers to the speed of light and f refers to the frequency of the radar signal. These values are important in determining the wavelength (λ) of the radar signal, which is used in calculating the beamwidth. The relationship between c, f, and λ is given by the equation λ = c/f. This means that as the frequency increases, the wavelength decreases, resulting in a narrower beamwidth for the radar. This is important in determining the resolution and accuracy of the radar's measurements.
