This report describes how the RCS of the radar target MQM-178, Firejet, is measured. The result is presented in figures showing RCS as a funcion of viewing angle for both X- and Ku-band. Some examples of high resolution ISAR pictures are also presented. The primary task was to measure the MQM-target modified with a taped nose cone. Additional measurements were also made with removed tape. The taped target has a significantly reduced RCS in the front sector.
