- Continuous wave (CW) radars show an excellent performance in high precision distance measurements. However, when it comes to absolute distances, the ambiguity of these systems is a notable issue. To extend the unambigous range beyond λ/2, dual tone systems have been presented using two spaced CW measurements. In this paper, a broadband multi-tone radar operating in the K-band using six-port technology is presented. By using more than two frequencies, the unambigous range can be further enlarged. The radar system presented in this paper is able to perform 5-FSK measurements within a bandwidth of 5.5GHz delivering an update rate of 25Hz and a precision of 37.96µm.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Since 1994, the multiport techniques were further developed for microwave and millimeter-wave radios. Until today, several multiport architectures for specific applications, such as communication transceivers, radar, sensing, direction of arrival estimation, or phase noise measurements, have been developed and implemented.This special issue highlights, through several examples and multiple references, some of the modern applications of the multiport technology and significant advances in fabrication procedures, in the recent years.
