摘要

A method for the purpose of determining the level of a background noise signals in the case of an analysis of an incident scheme that uses radio wave, the of a radar (2) are received and is converted into an electrical signal and a radar wave, by the radar (2) and transmitted by a within a measuring range of the radar (2) was reflected the target object, the method comprising the steps of:– Performing a frequency analysis with respect to the electrical signal in order to an intensity distribution of frequency components of the electrical signal to obtain;– Calculating a histogram of the intensities of the frequency components, which lie outside a predetermined frequency range, in which the response of the radar wave reflected by the target object should fall; and– Determining a of the intensities which in the intensity histogram of the frequency components describes a maximum value, as the level of the background noise signals.
