Formation RF (Radio frequency) Systems Compatibility is an important comprehensive ability that affects the survival and combat effectiveness of aircraft formation. It needs to be effectively assessed and verified through flight tests, and simulation can further optimize test design and improve test efficiency. Thus, a flight test method for formation RF systems compatibility based on simulation prediction is proposed in the paper。Firstly, the development trend of RF compatibility and is its capability requirements are summarized and analyzed. Secondly, a simulation model of formation RF systems compatibility based on interference conflict is proposed, and a flight test method of formation RF systems compatibility based on the interference conflict distance from simulation analysis is established. Finally, simulation analysis and flight profile design were conducted for a typical formation RF compatibility test. This study has provided an effective method for the test profile design and flight verification of formation RF systems compatibility.
