Electronic countermeasure simulation method with function level and signal level combined in real time

The invention provides a function-level and signal-level real-time combined electronic countermeasure simulation method, which aims at the simulation verification requirement of a new system interference technology on the influence of the overall combat effectiveness, sets key nodes and key frames related to the technology in an overall combat scene, and only performs signal-level simulation on the key frames of the key nodes, so that the whole combat effectiveness is simulated. And performing function-level simulation on the non-key nodes and the non-key frames of the key nodes. The two simulations are propelled according to the same time step length under the control of the same scene, the result of a key node in a key frame is obtained through processing of a signal-level simulation model, and the result of a non-key node and the result of the key node in a non-key frame are obtained through calculation of a function-level simulation model. And after the current simulation step length is processed, summari
