moving-target-indication radar

Also known as: MTI radar

Quick Summary

Moving-target indication (MTI) radar is a type of radar that detects moving targets. It operates by transmitting electromagnetic energy and observing the echoes returned from objects. MTI radar is particularly useful for distinguishing moving targets, such as aircraft, from stationary objects like ground clutter.12

The Doppler frequency shift is the key principle behind MTI radar. This shift occurs when there is relative motion between the radar and the target. By analyzing this frequency shift, MTI radar can filter out stationary echoes and focus on the signals from moving objects. This technology saw significant development after World War II and became vital for various radar systems, including those used for air traffic control and military applications.12
