A METHOD FOR ESTIMATING THE POSITION AND THE SPEED OF A TARGET WITH A RADAR EMITTING AN OFDM WAVEFORM

摘要

There is disclosed a methodfor estimating the position and the speed ofa target with a radar. The radar emits awaveform comprising a train of pulses, eachpulse comprising an OFDM chip constructedfrom subcarriers, the subcarriers coveringthe whole bandwidth of the radar. Uponreceipt of the echoed pulses, some of thesubcarriers are used in a step of Dopplerprocessing, each of said subcarriers beingfixed over the pulses. Upon receipt of theechoed pulses, other subcarriers, that arenot used for Doppler processing, are used ina step of High Range Resolution processing,the said subcarriers being randomly distributedover the pulses.
