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 pulsed radar used for?
Pulse radars are designed mainly for long distances. The main application is still the military area. Other applications include air traffic control, weather observation (especially precipitation radar) as well as the satellite-based remote sensing of the earth's surface.
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.
