A METHOD FOR MEASURING THE RADIAL VELOCITY OF A TARGET WITH A DOPPLER RADAR

摘要

The method comprises a step of transmitting an OFDM waveform comprising several frequency carriers transmitted simultaneously, the frequency carrier s being coded in order to improve the Doppler response. The method also comprises a step of receiving the waveform echoed from the target. The initial phase of each frequency carrier is recovered from the waveform echoed. The recovered initial phase of each frequency carrier is cyclically shifted in order to compensate for the Doppler effect and subsequently decoded. A compressed pulse is synthesized from the decoded initial phases.
