The invention discloses a helicopter satellite communication anti-rotor wing shielding key technology research method. The method comprises the following steps S01, enabling a sending terminal to divide a sending source code into a plurality of continuously arranged data segments; S02, performing dual time diversity on the modulated data segment; S03, establishing satellite communication channel models of the sending end and the receiving end; S04; combining the data segments after diversity and carrying out diversity, and sending the data segments through a communication channel model; and S05, enabling a receiving terminal to receive a code element, and acquiring a shielding time value of each rotor shielding period. In the present invention, according to the helicopter satellite communication anti-rotor wing shielding research method, a dual time diversity technology is adopted; the shielding time period value of the helicopter rotor wing on the satellite communication system duringdata communication can be detected, and the shielding influence of the helicopter rotor wing on the communication data in the satellite communication system is avoided, so that fading of the satellite communication data and loss of the data are avoided, and the accurate and complete communication quality of the helicopter satellite communication system is ensured.
