Title:
METHOD AND APPARATUS FOR DETERMINING NOISE FLOOR ESTIMATED VALUE, TARGET DETECTION METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/030556
Kind Code:
A2
Abstract:
Embodiments of the present disclosure provide a method and apparatus for determining a noise floor estimated value, a target detection method and apparatus, and an electronic device. The determining method comprises: obtaining a two-dimensional Fourier data plane corresponding to a linear frequency modulation continuous wave, wherein the two-dimensional Fourier data plane comprises a distance dimension and a Doppler dimension, and the distance dimension comprises a plurality of distance gates; and for each distance gate, determining a noise floor estimated value according to a plurality of two-dimensional Fourier transform energy data of the distance gate along the Doppler dimension. According to the technical solution provided by the embodiments of the present disclosure, the noise floor estimated value of each distance gate is determined, and the efficiency and accuracy of the determined noise floor estimated value are improved.
