    摘要: There is disclosed a method for estimating the position and the speed of a target with a radar.
    The radar emits a waveform comprising a train of pulses, each pulse comprising an OFDM chip constructed from subcarriers, the subcarriers covering the whole bandwidth of the radar.
    Upon receipt of the echoed pulses, some of the subcarriers are used in a step of Doppler processing, each of said subcarriers being fixed over the pulses.
    Upon receipt of the echoed pulses, other subcarriers, that are not used for Doppler processing, are used in a step of High Range Resolution processing, the said subcarriers being randomly distributed over the pulses.
    Application : detection
