Provided is a high-power pulse-signal radiation system. The system includes a pulse generating unit, a pulse radiation unit, a remote control unit, and a photoelectric conversion unit. The pulse generating unit use a DC power supply as a primary source, generate a pulse signal, and transmit a pulse signal to a radiation unit of an antenna through a high power coaxial cable. The pulse radiation unit receives the pulse signal generated by the pulse generating unit and radiates pulse energy corresponding to the pulse signal in a space. The remote control unit transmits an electric control signal required for controlling operation of the pulse generating unit.
