Radar Range Calculator
Calculate the maximum detection range of a radar system using the radar range equation
Typical RCS Values
- Bird: 0.01 m²
- Small aircraft: 1-2 m²
- Fighter jet: 1-5 m²
- Commercial aircraft: 10-100 m²
- Large ship: 10,000+ m²
- Stealth aircraft: 0.001-0.1 m²
Radar Range Equation
R_max = ((Pt × G² × λ² × σ) / ((4π)³ × P_min))^(1/4)
Where: Pt = transmit power, G = antenna gain, λ = wavelength, σ = RCS, P_min = minimum detectable power
