Claim 0:
1. A method comprising:
transmitting, from a device, a radar signal to a flying object, wherein the flying object comprises at least one rotary blade which enables the flying object to fly;
receiving, at the device, a reflected signal from the flying object, the reflected signal comprising a doppler signature caused by rotating movement of the at least one rotary blade; and
classifying the flying object by applying a machine learning algorithm to the reflected signal to yield a classification, wherein the machine learning algorithm is trained utilizing a respective doppler signature based on a respective rotating movement for each respective at least one rotary blade for each of a plurality of flying objects, wherein the respective rotating movement includes a first part in which the respective at least one rotary blade is moving towards the device and a second part in which the respective at least one rotary blade is moving away from the device.
