PURPOSE:To provide a battle technique evaluation system which obviates the necessity of increasing the number of ground stations, reduces the effects of the shadow of the airframe of a training airplane due to electric waves, and provides reliable data transmission. CONSTITUTION:A plurarity of measuring pods 2 and 3 to which different communication IDs are assigned are installed on a training airplane. A ground station is newly provided with an estimation part 6 which determines which of the measuring pods 2 and 3 on the same airframe has higher reception probability, and a setting part 7 which rewrites a communication ID in a data send instruction signal according to a setting signal from the estimation part 6, in addition to a conventional battle technique evaluation processing part 9. This constitution allows airframe conditions to be continuously and stably monitored by selectively using the measuring pod 2 or 3 which is not in the blanking area of the airframe.
