Smooth function-based secondary radar responder power control method

The invention discloses a smooth function-based secondary radar responder power control method, and the method comprises the following steps: S1, building a radio signal measurement model which is used for calculating the distance R_C between an aircraft platform and a secondary radar when the aircraft platform receives a secondary radar signal; s2, when a secondary radar signal is prepared to be transmitted, calculating the distance difference delta Rx between the distance between the aircraft platform and the secondary radar and the distance R_C; and S3, according to the distance difference delta Rx, calculating the transmitting power when the aircraft platform transmits the secondary radar signal. According to the method, effective radiation control is performed on the transmitting power of the responder in the secondary radar, so that the stealth capability of the radiation source is improved to the greatest extent on the premise of not influencing the overall efficiency, and the maximum combat effectiven
