Final answer:
The easiest method to eliminate MTI blind speeds is by using staggered or random PRFs, which alter the pulse repetition frequencies to ensure that moving targets do not consistently align with the radar's blind spots.
Step-by-step explanation:
The easiest method for eliminating MTI (Moving Target Indicator) blind speeds is to use staggered pulse repetition frequencies (PRFs). By alternating the pulse repetition frequency, you can ensure that targets do not fall into the blind speeds of the radar. Blind speeds occur when a target's Doppler frequency is a multiple of the radar's PRF, causing the radar to not detect the target's movement. To counter this, the PRF is changed periodically so that the target's Doppler does not consistently align with the radar's blind speeds. Another technique is to employ random pulse repetition intervals (PRI), which introduce variability in the transmitting pulses, making it less likely for targets to consistently align with blind spots. Doppler filtering might also be used to separate stationary and moving targets and adjust for blind speeds dynamically.
