By utilizing the characteristics of tethered drones or medium to large unmanned aerial vehicles that remain in the air for a long time, and carrying corresponding payloads, an air interference support environment is constructed to provide a realistic and realistic simulation of the complex electromagnetic environment close to actual combat for experimental training tasks. The electromagnetic environment and terminal area of the experimental training area are continuously monitored on a large scale, and various electromagnetic signals in the environment are collected and stored in real time to achieve target reporting, real-time video transmission, and playback, Plan design, optimization, and effectiveness evaluation to support experimental training tasks.
