Radar Range Calculator

This calculator calculates the maximum range of a radar based on the power transmitted, system gain and receiver sensitivity. This is an theoretical approach to the calculation and can be used to make rough approximations. There are many other factors that will come in to play when doing this in the real world. It is a good starting point.

Calculate the Maximum Range of a Radar

  • Pulse Peak Power (Pt)
  • Maximum Power Gain (G)
  • Antenna Aperture (Ae)
  • Radar Cross Section Area
    Sq. Mts
  • Detectable Signal (Pmin)
  • Calculate Reset


  • Range (Rmax):
