MTI (moving target indication) radar and Doppler radar are both types of radar systems used to detect and track moving targets, but they operate based on different principles and techniques. MTI radar primarily uses pulse cancellation techniques to eliminate stationary or clutter echoes from radar yields, focusing on detecting moving targets based on changes in their position between radar pulses.
It uses coherent processing to compare successive radar returns and distinguish between moving and stationary targets.
Pulse Doppler radar, on the other hand, combines traditional pulse radar with Doppler radar principles. It uses pulses of radio waves to measure the target range and uses Doppler shifts in radar returns to detect the target speed. Pulse Doppler radar can distinguish between stationary and moving targets by analyzing the frequency shift (Doppler shift) caused by the movement of the target relative to the radar.
This type of radar is particularly effective at detecting targets at long ranges and in cluttered environments.
Yes, the Doppler effect is used in MTI radar systems. Although the MTI radar primarily focuses on canceling stationary clutter, it also uses Doppler processing to detect and track moving targets. The Doppler effect helps MTI radar systems distinguish between moving targets and stationary clutter by analyzing the frequency shift in radar returns caused by the movement of targets relative to the radar.
By filtering out clutter echoes and focusing on Doppler-shifted yields, the MTI radar improves its ability to effectively detect and track moving targets in various operational scenarios
