Radar Range Equation
Received echo power for a monostatic radar, combining transmit power, antenna gain, target size and range.
Formula
Variables
Example
Doubling range cuts received power by 2⁴ = 16× (−12 dB)
Did You Know?
The brutal R⁴ dependence means detecting a target at twice the range needs sixteen times the power — and is exactly why stealth aircraft chase tiny radar cross-sections instead.

BasicMaximum line-of-sight range to the radio horizon for a VHF antenna, driven by antenna height and the curvature of the Earth.
Radio Wavelength
BasicWavelength of a radio signal is the speed of light divided by its frequency; it sets antenna length and dish sizing.
DME Slant Range Correction
BasicDME measures the direct (slant) distance to the beacon; the true ground distance is found by removing the height component.
ILS Glideslope Height

One-in-Sixty Rule
BasicRule-of-thumb linking a lateral track error to an angular deviation: 1 nm off after 60 nm is about 1° of error.
Mode C Altitude Reporting
BasicA Mode C/S transponder reports pressure altitude referenced to 1013.25 hPa; dividing by 100 gives the flight level, independent of the local altimeter setting.
