Range detection applications based on radar can be separated into measurements of short distances with high accuracy or large distances with low accuracy. In this paper an approach is investigated to combine the advantages of both principles. Therefore an FMCW radar will be extended with an additional phase evaluation technique. In order to realize this combination an increased range resolution of the FMCW radar is required. This paper describes an frequency estimation algorithm to increase the frequency resolution and hence the range resolution of an FMCW radar at 24 GHz for a line based range detection system to evaluate the possibility of an extended FMCW radar using the phase information.
