What is MTI in radar system?

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.

What is an advantage of using MTI?

Benefits or advantages of MTI Radar ➨MTI radar can distinguish between moving target and stationary target. ➨It uses low PRF (Pulse Repetition Frequency) to avoid range ambiguities. ➨MTI principle is used in air surveillance radar which operates in presence of clutter. ➨It is simpler compare to pulse doppler radar.

What is the difference between MTI and MTD?

The difference between MTI and MTD in short In a simplified explanation, we can say that MTI is the older version and MTD the newer version. Both eliminate static clutter from the radar image to brush out the moving aircraft. MTI is a filter, MTD is a composite algorithm, composed of several subfunctions.

How many mixers are used in MTI radar?

The output of Local Oscillator is applied to both Mixer-I and Mixer-II. Coherent Oscillator − It produces a signal having an Intermediate Frequency, fc. This signal is used as the reference signal. The output of Coherent Oscillator is applied to both Mixer-I and Phase Detector.

What is blind speed in radar?

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.

What is the necessity of Doppler filter banks used in MTI radar?

The Doppler filters immediately produce an output signal during the current pulse period. These filters are thus also effective in the long-range with only one pulse period per antenna direction. They are then used to measure the Doppler frequency and thus directly to measure the radial velocity of the target.

What is non coherent MTI radar?

Non-Coherent MTI Radar The echoes from moving target involves both amplitude and phase changes. In non-coherent MTI radar, change in amplitude is considered. The output of IF amplifier is passed to amplitude detector and detector output is given to delay line canceller.
