Title:
METHOD FOR ELIMINATING ONE-BIT SIGNAL HARMONIC FALSE TARGET, AND RELATED COMPONENT
Document Type and Number:
WIPO Patent Application WO/2022/012213
Kind Code:
A1
Abstract:
A method for eliminating a one-bit signal harmonic false target, and a related component. The method comprises: performing dechirping, frequency shifting, one-bit quantification, AD sampling and Fourier transform processing on an echo signal to obtain a spectrum; then performing constant false alarm rate detection on the spectrum, so as to obtain the distance of a real target and the distance of a false target; and for the distance of the false target, performing a difference comparison on angle-of-arrival information based on multiple snapshots and angle-of-arrival information based on a single snapshot, obtaining, from the angle-of-arrival information based on the single snapshot, a distance that corresponds to the angle with the smallest angle difference, and using the distance as the distance of the real target (S207), thereby eliminating the false target. Data collection is performed by using a lower sampling rate, thereby greatly reducing the data volume, and achieving the aims of simplifying a radar system structure, reducing the complexity of a system, and reducing the costs of data collection, transmission, storage and processing.
