Aiming at the demand for emergency communication system with strong anti-interference capability in Modern Warfare the high power microwave emergency communication technology is studied. According to the principle of modern communication,the principle of modern communication anti-jamming and the characteristics of high power microwave signals,A battlefield emergency communication scheme with strong anti-interference capability is designed. Based on the characteristics of high power microwave signal,such as high peak power,narrow pulse width and low pulse repetition rate,the energy of signal will be concentrated in narrow pulse. Applying high power microwave signal to communication can effectively improve the anti-jamming capability of communication. High power microwave communication is realized by pulse width modulation（ PWM） which is suitable for the characteristics of high power microwave signals. The feasibility of high power microwave communication is verified by Simulink simulation. The anti-jamming capability of high power microwave communication is analyzed by MATLAB numerical experiment and the anti noise performance curve of high power microwave communication is obtained. The results show that when the signal to noise ratio is greater than-5 dB,under the same signal to noise ratio,the high power microwave communication can lower the system error rate and improve the anti-interference ability of the communication compared to 2 ASK,2 FSK and 2 PSK. Therefore,high power microwave emergency communication technology provides a new solution for battlefield emergency communication system,and has important military application value.
