This converter allows you to calculate the maximum range of a radar from the output power, the antenna gain, the frequency, the radar cross section and the minimum detectable signal. It provides a realistic estimate of the distance at which an object can be detected, useful for planning and analyzing radar systems.
Formula
R = ((Pt × σ × c² × G²) / ((4 × π)³ × f₀² × Pmin))^(1/4)
Explanation of the formula
The formula uses the transmitted power Pt, the antenna gain G, the working frequency f₀, the effective section σ of the target and the minimum signal Pmin. The speed of light c allows us to relate frequency to wavelength. We first calculate the numerator to denominator ratio, then we take the fourth root to obtain the range R in meters.
Uses
- Evaluate the maximum detection distance of a radar for different types of targets.
- Compare the performance of different antennas and transmitting powers.
- Plan radar coverage and security in surveillance systems.
- Optimize radar parameters based on operational conditions and detection requirements.
