Abstract
Therefore, measurement range of the velocity is limited due to the transmitted LPM signal. In this paper, low-calculation-cost Doppler-shift compensation and high-resolution Doppler velocity estimation with wide measurement range are proposed. A pair of LPM signals, which includes two down-chirp LPM signals, is transmitted in the proposed method. The received signal is correlated with the single reference LPM signal using cross-correlation by single-bit signal processing. The distance and the Doppler velocity of the object are estimated from the modulated crosscorrelation function with the low calculation cost.
