How does a pulse Doppler radar work?

Doppler radar

By measuring the shift (or change) in phase between a transmitted pulse and a received echo, the target's movement directly toward or away from the radar is calculated. This then provides a velocity along the direction the radar is pointing, called radial velocity.

Is pulse radar and pulse Doppler the same?

Pulse radar

The pulse Doppler-radar has the advantage of being able to detect small amplitude moving target returns against a large amplitude clutter background. Pulse-delay ranging is based on the measurement of the time delay between the transmitted pulse and the received echo.

What is pulse radar used for?

Pulse radar has important functions in air traffic, naval and military object detection, weather surveillance and space exploration, among other uses. The predecessor for the pulse radar system was the monopulse radar, which has the ability to approximate an object's location and position from a singular pulse.

What is difference between MTI and pulse Doppler radar?

The MTI radar has a pulse repetition frequency low enough to not have any range ambiguities. It does however have many ambiguities in the Doppler domain. The pulse Doppler radar, on the other hand, is just the opposite. It has a prf large enough to avoid Doppler ambiguities, but it can have numerous range ambiguities.
