Example Calculation

INPUTs:

  • Antenna Diameter = 5 meters
  • Radar Frequency = 10 GHz

OUTPUT:

  • Radar Beamwidth = 0.42 degrees

Radar Beamwidth Formula

The following formula is used to calculate radar antenna beamwidth:

Antenna Beamwidth = 70 * (λ/D)

Where:

  • D = Diameter of Antenna
  • λ = Wavelength (calculated as c/frequency)
  • c = Speed of Light (approximately 3 x 108 meters per second)
