Abstract

The method involves measuring the reception spectra in at least one target-containing reception sector and target-free reception sector. A model is used to calculate the dispersion loss as a function of frequency for an estimated target distance. The target distance is output when the agreement between a measurement target level and a target-specific signal level reaches a predetermined degree.
