Equation 1. The Probert-Jones Radar Equation. Click for Long Description.

Where:

Pr = power returned to the radar from a target (watts)

Pt = peak transmitted power (watts)

G = antenna gain

greek symbol theta = angular beamwidth

H = pulse length

greek symbol pi = pi (3.141592654)

K = physical constant (target character)

L = signal loss factors associated with attenuation and receiver detection

Z = target reflectivity

greek symbol lambda = transmitted energy wavelength

R  = target range
