This calculator determines the blind speed of a radar as well as the wavelength of the signal. It helps identify how quickly a target becomes temporarily undetectable, when the Doppler shift matches the radar pulse repetition frequency.
Formulas
λ = c/f
v = (λ × 10⁹) / (2 × PRT)
where c = 299792458 m/s
Explanation of formulas
The first formula calculates the wavelength λ of the radar signal as a function of its frequency f. Then, the blind speed v is calculated from λ and the pulse repetition period (PRT). This speed corresponds to the point where the radar cannot distinguish movement due to the synchronization of its pulses.
Uses of the calculator
- Determine the speeds of invisible targets for a given radar.
- Optimize frequency and PRT parameters in radar systems.
- Analyze the performance of pulse radars.
- Practical tool for telecommunications and defense engineers.
