Claim:
1. A method for detecting a target based on a frequency modulated continuous wave (FMCW) radar including a processor, the method comprising: transmitting, by the processor, a sensing signal for detection of the target, and receiving, by the processor, a response signal in response to the sensing signal; performing, by the processor, a signal processing on the response signal, and generating, by the processor, a frequency spectrum of a beat signal; determining, by the processor, a detection frequency band for detection of the target within a valid frequency band of the frequency spectrum; determining, by the processor, a threshold value to determine a target detection peak value for detection of the target among peak values of the frequency spectrum; and detecting, by the processor, the target based on the detection frequency band and the threshold value, wherein the detection frequency band corresponds to a frequency band obtained by excluding a frequency band corresponding to frequencies which are greater than a frequency of a greatest peak value among the target detection peak values, from the valid frequency band.
