Abstract: In order to understand the communication station interference patterns in continuous wave irradiation zone and the interference mechanism of communication station in a continuous band, through building the test platform, we carried out the interference test of a certain type of VHF communication station using irradiation on radio different parameters under the action of interference patterns. The experimental results show that the frequency range of the ultra short wave radio is 30 KHz, the higher frequency signal is more susceptible to interference under the same condition, and the increase of receiving power can effectively improve the anti-jamming ability.
