How the problem of blind speed in MTI radar can be overcome by use of multiple PRF?

One solution to the blind speed problem is to use nonuniform PRFs (staggered PRFs). Adjacent pulses are transmitted at different PRFs. Such a configuration pushes the lower bound of blind speeds to a higher value.

What are the limitations of MTI radar?

Drawbacks or disadvantages of MTI Radar

Following are the disadvantages of MTI Radar: ➨Blind speed does not get detected by pulse MTI radar. Blind speed is defined as magnitude of radial component of velocity of target when moving target appears as stationary target. ➨They can have doppler ambiguities.

What is MTI radar used to remove due to constant target?

A typical MTI radar uses a high-pass filter to remove energy at low Doppler frequencies. Since the frequency response of an FIR high-pass filter is periodic, some energy at high Doppler frequencies is also removed. Targets at those high Doppler frequencies thus will not be detectable by the radar.

Which display is used in MTI radar?

The moving target indicator (MTI) radar is a pulsed radar that uses the Doppler frequency shift as a means for discriminating moving targets from stationary clutter.
