Title:
SIGNAL PROCESSING APPARATUS AND METHOD USING VEHICLE RADAR SENSOR, AND COMPUTER-READABLE RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/251637
Kind Code:
A1
Abstract:
Provided are a signal processing apparatus and method using a vehicle radar sensor, and a computer-readable recording medium. The signal processing apparatus using the vehicle radar sensor may comprise: an RF module which generates a beat frequency signal that is a difference frequency between a transmitted FMCW signal and an FMCW signal received by being reflected by an object whose movement or position including a movement changes over time; a signal processing module which generates an image having a micro-Doppler frequency change pattern on the basis of the generated beat frequency signal; and a CNN module which classifies the object according to the generated image having the micro-Doppler frequency change pattern.
