In order to investigate the generation of high power electromagnetic pulse, a high power electromagnetic pulse radiation setup is developed in this paper. In the setup a high power pulse driving source with high output impedance based on Tesla transformer is utilized as charging source, and the subnanosecond pulse conditioning and radiation is realized by using transmission line charging technology and double ridged horn-shaped antenna connected with impedance transformer respectively. High power electromagnetic pulses with pulse repetition frequency （PRF） reached 100Hz and maximum field-range product equal to 294KV can be achieved by the setup. The spectrum of radiated pulse is concentrated in 0.4 - 1.0GHz.
