Radar device for frequency-modulated continuous waves has a receiver, a beat-signal device, a means of generating correlation matrices and a means of storing previous correlation matrices

摘要

A receiver (12) picks up a reflected signal. A device (14) creates beat signals based on the reflected signal. Another device (18) calculates correlation matrices based on the beat signals. A memory device (21) stores previous correlation matrices. An adding device calculates correlation matrices to be added up and it adds correlation matrices to the previous correlation matrices.
