Moving target indication (MTI) is a mode of operation of a radar to discriminate a target against the clutter. [1] It describes a variety of techniques used for finding moving objects, like an aircraft, and filter out unmoving ones, like hills or trees.

MTI processing uses MTI filters to remove low-frequency components in slow-time sequences. Because land clutter usually is not moving, removing low-frequency components can effectively suppress it. The three-pulse canceler is a popular and simple MTI filter.

Moving targets change in amplitude from one pulse to the next because of their Doppler frequency shift. Pulse Doppler filtering on groups of 8 or greater pulses with a fine grained clutter map. Aircraft are detected in ground clutter and / or rain with the Doppler filter bank & use of 2 PRFs. Courtesy of Northrop Grumman Used with permission. Why?

This example shows how to generate surface clutter and target returns for the simulation of a moving target indicator (MTI) radar in a radarScenario. MTI filtering is performed and the resulting range profiles and Doppler spectra are examined.

Moving Target Indicator (MTI) and Pulse-Doppler (PD) processing use the Doppler shift of the different signals to enhance detection of moving targets and reject clutter. Unambiguous range is inversely proportional to the PRF. The PRF is twice the Doppler frequency of the target signal.

This paper presents an adaptive MTI filter with improved performance in non-stationary clutter environment. Non-stationary clutter processes are characterised by space/time dependent statistics. An estimator for the pulse to pulse amplitude variations of the clutter process is therefore introduced.

This paper discusses digital filters for moving-target indicator (MTI) radars. The digital MTI filter, implemented with video storage and cancellation, avoids the shortcomings of traditional analog filter systems and offers several important advantages, including freedom in the choice of the interpulse period.
