Moving object detection method in real-time using FMCW Radar

摘要

The present invention relates to a moving target detection technique, and more specifically, to a real-time moving target detection method using a frequency modulated continuous wave radar for detecting a moving target in real time by using robust principal component analysis (RPCA) through gradient descents, which comprises: a step of collecting input data by extracting fast Fourier transform (FFT) information from a reflection signal received to the frequency modulated continuous wave radar in a detection area; a preprocessing step of performing compensation and correction on the collected input data; a step of modeling a lower noise background by using RPCA through gradient descents in order to separate a noise background and foreground moving objects corresponding to a moving target with respect to the preprocessed data; and a step of detecting a position of the foreground moving objects without noise by performing automatic multiscale-based peak detection (AMPD) after applying the RPCA.
