Pulse compression, and moving target indicator ( MTI ) provide up to 25 dB sub-clutter visibility.
2.
Radar can also merge with other sensors to give even more information, such as # Moving Target Indicator.
3.
Moving target indicator signal sampling process . Moving target indicator ( MTI ) begins with sampling two successive pulses.
4.
Moving target indicator signal sampling process . Moving target indicator ( MTI ) begins with sampling two successive pulses.
5.
Moving target indicator is generally required for acceptable performance near terrain, but this introduces radar scalloping issues that complicate the receiver.
6.
Doppler has maximum detrimental effect on moving target indicator systems, which must use reverse phase shift for Doppler compensation in the detector.
7.
Low PRF radar intended for aircraft and spacecraft detection are heavily degraded by weather phenomenon, which cannot be compensated using moving target indicator.
8.
Doppler weather effects ( precipitation ) were also found to degrade conventional radar and moving target indicator radar, which can mask aircraft reflections.
9.
This phenomenon also has detrimental effect on moving target indicator systems, where the detection scheme subtracts signals received from two or more transmit pulses.
10.
This also implemented a moving target indicator that suppressed clutter, but it was recognized that an MTI signal would not be available in a noncooperative environment.
