What is MTI in 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.
What is MTI radar working principle?
Principle: When it is desired to remove the clutter due to stationary targets an MTI radar is employed. The basic principle of MTI radar is to compare a set of received echoes witrh those received during the previous sweep. Moving targets will give change of phase and are not cancelled.
What is an MTI radar and how does it operate?
This type of Radar is called Moving Target Indicator Radar or simply, MTI Radar. According to Doppler effect, the frequency of the received signal will increase if the target is moving towards the direction of Radar.
What is the difference between MTD and MTI?
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 does radar calculate a target’s distance?
Distance is determined by measuring the time it takes for the pulse to make a round trip from the radar to the target and back using the relation distance = (time) * (velocity). The velocity is the speed of light, the speed at which the pulse travels (c).
What is the meaning of MTI from a moving platform?
Moving target indication (MTI) is a mode of operation of a radar to discriminate a target against the clutter. It describes a variety of techniques used to find moving objects, like an aircraft, and filter out unmoving ones, like hills or trees.
What are the different types of MTI radar?
There are two basic types of MTI radars, namely coherent and non-coherent MTI. The coherent MTI radar differentiates moving targets from stationary targets by using the Doppler shift passed on to the reflected signal by a moving target.
What kind of radar is a moving target indicator?
This type of Radar is called Moving Target Indicator Radar or simply, MTI Radar. According to Doppler effect, the frequency of the received signal will increase if the target is moving towards the direction of Radar.
How are moving targets detected in a MTI system?
In coherent MTI systems, the Doppler shift in the echo signal from the moving target is used to differentiate it from stationary target. But in non-coherent MTI systems, the moving targets can be detected by observing the relative motion between the target and clutter background, and also by observing corresponding changes in amplitudes of pulses.
What causes lower improvement factor on MTI radar?
High equipment instabilities cause lower improvement factor of MTI radars. The MTI radar can be limited by internal fluctuations of clutter (clutter from trees, rain, chaff, and sea). Due to limiter in MTI radars, performance may be degraded.
