pulse doppler radar and MTI radar both are used to find
the target range by using doppler effect( doppler
shift) .but MTI radar uses low PRF whereas pulse doppler
uses high PRF.

Answer / ali menbet

The different between MTI radar and PD radar is a unique
even though they all relay on Doppler principle , but the
MTI radar determine moving targets by detecting the phase
and amplitude of the received wave and compare it with
saved replica of the original transmitted wave but at
opposite phase , so if the target are not moving then the
phase and amplitude of the 2 signals will match but at
different value will result of canceling each other , but
if the 2 signals are not matched they will give positive or
negative value and that is indication of moving target.

Pulse Doppler radar has anther interest , it is interested
in the changes happen to the transmitted wave (DOPPLER
SHIFT), either it will be compressed if the target moving
toward the radar
( example: received frequency may change from transmitted
6000MHz to 6010MHZ ),
or may stretch if the target are going away from the radar
( the 6000MHz will be 5990MHz ).

The PD radar are not interested in the transmitted
frequency any more after it has been transmitted but it
does set filters around it at the expected reflected
frequency
( example:5970,5980,5990,6010,6020,6030 (
If there are moving targets then the filters will receive
power and that is an indication of presence of target.

That is my understanding , however I'd like to hear from
you if you have anther opinion.

Answer / lodhi

pulse doppler radar , in this the radar send the pulse
train to detect the position of target and MTI(moving
target indicator) in which it detect the target which is
moving but pulse radar can detect the moving target but
there is a disadvantage that the problem of blind speed
arises and pulse radar dosn't continuosly transmit the
pulse after transmitting wait for receiving in ths time it
doesn't transmit any pulse...
