Calibration of Transmitting and Receiving Array of a Radar using MIMO Measurement

This paper presents a simple method allowing to extract information of unknown phase offsets between elements of transmitting and receiving antenna arrays in a collocated MIMO radar. It is shown how to extract independent vectors of phase offsets between receiving and transmitting elements using nor...

Summary:This paper presents a simple method allowing to extract information of unknown phase offsets between elements of transmitting and receiving antenna arrays in a collocated MIMO radar. It is shown how to extract independent vectors of phase offsets between receiving and transmitting elements using normalization with averaging as well as SVD decomposition of measurement matrix obtained for observation of calibration target placed at the known angular position.
