What is a disadvantage of MTI radar systems?

The selected answer, blind speed, refers to a limitation inherent to Moving Target Indicator (MTI) radar systems. Blind speed occurs when the radar cannot detect moving targets that are traveling at a specific speed due to the way the radar processes returns from moving objects. This phenomenon arises because the radar's Doppler filtering can effectively nullify the signals from targets moving at certain speeds, making them "invisible" to the system. This is significant in air traffic control and other applications because if an aircraft or vehicle is traveling at a speed that coincides with the blind speed, it could go undetected, potentially leading to hazardous situations, particularly in busy airspace. Therefore, understanding and recognizing blind speed is crucial for the reliable operation of MTI radar systems. Other options, while they may describe different radar issues, do not pertain specifically to the unique operational limitation caused by MTI radar signal processing. Range ambiguity relates to interpreting multiple targets at similar distances, inaccurate altitude data typically involves issues with altitude measuring systems rather than MTI functionality, and high operational costs may not directly correlate with the performance limitations of MTI radar but rather relate to overall system expenses.
