In recent years, several papers related to the detection, classification and tracking of human using Doppler radar
for surveillance, security and civil applications have been published1-8. The main advantage of using radar that it can
efficiently operate in the darkness, at long range and almost all climate situations.
The micro-Doppler signature from human body parts are different for walking, running, jumping and other
activities. So it is easy to determine the human activity using micro-Doppler radar2
.
By analyzing the Doppler signature, one can also get information such as velocity of different body parts, stride
length, etc. of the target. Also, it is possible to classify the target is either human or animal because the stride length
and velocity of animal are unlike to that of human2, 3.
