Maximum Range Radar Target RCS Area Transmit Signal Return Echo Radar Maximum Range

Formulas

R = ⁴√((Pt × G² × σ × c²) / (Smin × (4π)³ × f²))
Pt = Radar output power in watts
G = Antenna gain in linear value
σ = Radar cross sectional area in m²
c = 3 × 10⁸ m/s
f = Frequency in Hz
Smin = Minimum detectable signal in watts

Diagrams & Theory

Radar maximum range depends on transmitted power, antenna gain, target radar cross section, frequency and receiver sensitivity.

Higher output power, higher antenna gain and larger target area increase range. Higher minimum detectable signal or higher frequency can reduce the calculated range.

Example

Input Example

Output Power: 10 W
Antenna Gain: 30 linear
Frequency: 10 GHz
RCS Area: 1 m²
Minimum Detectable Signal: -90 dBm

Output

The calculator converts all values to base units and gives maximum radar range in meters and kilometers.
