The blind speed is a radial speed of the airplane at which the phase shifting of the echo-signal has the value ±n · 360° between two pulse periods. With blind speeds moving targets are suppressed by a MTI system like ground clutters.

The radar blind speed is the speed at which the target will not be visible to the radar. This speed can be calculated based on the frequency/wavelength of the wave and the Pulse Repetition Time.

Range ambiguity resolution is a technique used with medium pulse-repetition frequency (PRF) radar to obtain range information for distances that exceed the distance between transmit pulses.

Blind Speed is a very serious problem in MTI Radar. When the Doppler shift equals an integer multiple of PRF (Pulse Repetition Frequency), the delay line canceller not only eliminate the DC components caused by the clutter but it also rejects moving targets.

Using multiple PRFs allows targets, whose radial velocity corresponds to the blind speed at 1 PRF, to be detected at another PRF. PRFs may be changed from scan to scan, dwell to dwell, or from pulse to pulse (Staggered PRFs)

By employing techniques such as PRF diversity, staggered PRFs, continuous wave radar, multiple frequencies, and advanced Doppler processing, radar systems can effectively reduce the impact of blind speeds and improve target detection across a range of velocities.

The blind speed refers to situation where doppler shift of radar signal is unable to accurately detect the speed or velocity of a target. Blind speed occurs when doppler shift is equal to or very close to zero, making it difficult for radar system to determine the target's speed accurately.

This CalcTown calculator calculates the radar blind speed according to the blind speed equation. If the Doppler frequency produced by a moving target is exactly the same as PRF, then sampling occurs at the same point in each cycle.

Understanding radar blind speed is essential in radar system design, ensuring reliable detection and minimizing vulnerabilities in radar-based monitoring and tracking applications. Calculate radar blind speeds using the formula: v_n = n * (c * PRF) / (4 f_0).
