Abstract
An apparatus for detecting a target is disclosed. The apparatus of detecting a target includes: a frequency mixer configured to calculate a first beat frequency based on a transmitted signal and a received signal of first scanning and calculate a second beat frequency based on a transmitted signal and a received signal of second scanning performed with a predetermined time interval from the first scanning; a controller configured to extract a first moving component by comparing an up-chirp period frequency and a down-chirp period frequency of at least one of the first beat frequency or the second beat frequency; extract a second moving component by comparing up-chirp period frequencies or down-chirp period frequencies of the first beat frequency and the second beat frequency; and determine the moving target based on the first moving component and the second moving component.
