摘要：
A peak detecting threshold determining method is provided which determines a peak detecting threshold which is used by an FMCW radar in detecting a peak frequency component which appears as representing a target object in a frequency spectrum. A CW radar wave is transmitted to produce a CW noise spectrum. An offset is added to frequency components in a high-frequency region of the CW noise spectrum to define a first distribution as a value of the peak detecting threshold. This enables the value of the peak detecting threshold in the high-frequency region to be determined with high precision by reflecting a receiver noise containing a leakage noise.
