The invention relates to a simplified unmanned aerial vehicle-mounted high-power microwave threat alarm module, which is characterized in that a special step-down amplitude limiting unit is arranged for reducing microwave peak power after antenna coupling and preventing high-power microwaves from directly damaging subsequent circuits of the alarm module according to the occasional, short pulse width, instantaneous high power and other characteristics of the high-power microwaves. A wide dynamic detection circuit is adopted to detect high-power microwave envelope online in real time, a detection value is compared with a threshold value adjusting circuit, and it is guaranteed that the recognition and comparison unit can accurately recognize high-power microwave threats. After the method is adopted, the unmanned aerial vehicle can obtain a rapid alarm signal after entering a high-power microwave area, the unmanned aerial vehicle and an unmanned aerial vehicle swarm can rapidly break away from the area by adopting the modes of avoiding, returning and the like, and the survival ability of a battlefield is remarkably improved.
