Abstract

A radar method comprising transmitting and receiving signals simultaneously or overlapping in time by spatially separated transceiver units. Comparison signals are formed from transmitted and received signals by respective transceiver units. A phase correction is formed for each of a plurality of sample values, to generate a measure of phase difference per sample value between the comparison signals. A measure of phase difference is used to improve accuracy of distance or velocity measurements between the transceiver units. A radar system includes transceiver units and an evaluation unit configured to perform the method.
