Up to now, theoretical investigations have shown that switching between parts of the transmit and/or receive aperture in a pulse-to-pulse cycle improves the GMTI performance of a two-channel radar system. This paper intends to verify experimentally the GMTI capability of the switching concept for the first time. Accordingly, three different GMTI modes were implemented in the PAMIR system including two switching modes. An experiment was conducted using six cooperative vehicles following a predefined scenario to compare the GMTI performance and in particular the positioning accuracy of the different GMTI modes. The results of this experiment are presented in this paper.
