Radar Range Calculator Radar Range Calculator Radar Range Calculator Transmitter Power (W) Antenna Gain Radar Cross Section (m²) Minimum Detectable Power (W) Calculate Understanding Radar Range Calculation The maximum radar range is determined by the radar equation: Rmax = (PtG2σλ2 / (4π)3Pmin)1/4 Where: Rmax: Maximum radar range Pt: Transmitter power G: Antenna gain σ: Radar cross section of the target λ: Wavelength (implicit in our simplified calculator) Pmin: Minimum detectable power Example Calculation: Let's consider a typical air traffic control radar: Transmitter Power: 1000 W Antenna Gain: 10000 (40 dB) Radar Cross Section (small aircraft): 1 m² Minimum Detectable Power: 10-13 W Using these values in the calculator would yield a maximum range of approximately 240 km. Factors Affecting Radar Range: Transmitter Power: Higher power increases range Antenna Gain: Better focusing of energy improves range Target RCS: Larger targets are detectable at greater distances Receiver Sensitivity: Lower minimum detectable power increases range Experiment with the calculator to see how changing these parameters affects the maximum radar range!
