Abstract
In a method for the determination of the unambiguous range for the measurement of the IF deviation in a frequency-regulated radar system, a frequency adjustment or tuning of the radar system is carried out during the reception of an echo signal by adjustingly setting respectively at least one value for the IF deviation around the value zero in the unambiguous range of the IF deviation as well as in an ambiguous range of the IF deviation. Then, the unambiguous range is recognized as such by comparison of the signal amplitude and/or the number of the detected targets during these adjustment settings, because the unambiguous range exhibits the highest signal amplitude and/or the greatest number of detected targets (i.e. echo signals).
