RADAR APPARATUS

原文（中国語）

A radar apparatus comprising one or more processors configured to: receive radar data comprising a plurality of samples representing the reflections of transmitted radar signals from one or more targets having been received by one or more antennas, the transmitted radar signals comprising a series of frequency stepped chirps; calculate a Doppler FFT based on the radar data by determining a Fourier transform of respective first-groups of the samples of the plurality of samples, wherein each first-group comprises a sample from each of the chirps of the series of chirps from a corresponding time-point during the respective chirp, to generate Doppler-FFT data; perform autoregressive linear prediction, wherein said autoregressive linear prediction is respectively applied to the samples of each chirp as represented in the Doppler-FFT data to generate extrapolated Doppler-FFT data; perform further processing to determine range and/or velocity of the targets based on the extrapolated Doppler-FFT data.
