Abstract: In order to carry out data link performance index test more reasonably and efficiently, a test method based on wired injection method is proposed. The method is applied to the performance index test of a certain type of UAV data link, and the experimental results of data link transmission rate and transmission delay are obtained. In order to evaluate the test results the evaluation hierarchy structure of the uplink index of a certain type of UAV data link is established, the utility function of the normalization of different types of test results is proposed, and the judgement matrix of the weight coefficients of different indicators is constructed. The method of analytic hierarchy process (AHP) is applied to evaluate the effectiveness of a certain type of UAV uplink, which can provide guidance for the performance test and effectiveness evaluation of measurement and control data link equipment.
