In this paper, the factors that affect the communication distance index in the test of ultrashort wave communication distance are analyzed. Based on the radio wave propagation loss model, the ground test method and method of the ultrashort wave communication distance are designed and applied in the practice of flight test. The method realizes the initial verification of the communication distance performance index in the ground test, improves the flight test efficiency and reduces the test flight cost.
