In military applications, the above system is often affected by an interference signal generated by an interference signal generating device arranged on an enemy aircraft, so that normal communication signals between the two signals cannot be accurately transmitted. Existing analog jamming signal generating devices are typically fixed in position and the jamming signal transmissions are directed to a fixed alignment signal receiver. The analog interference signal generated by such an analog interference signal generating device is greatly different from the interference signal actually produced by enemy. The directional communication system is improved according to the analog interference signal, and expected effects are difficult to achieve. Therefore, how to improve the analog interference signal generating device so that the influence of the generated analog interference signal on the directional communication system is more close to the actual interference signal has become a problem to be solved in the art.
