The invention relates to the field of UAVs (Unmanned Aerial Vehicles) and particularly relates to an interference-type anti-UAV system which comprises a detection unit, a cradle head unit, an interference unit and a main control unit, wherein the detection unit is used for performing scanning detection on a low-altitude region and transmitting monitoring information in real time; the cradle head unit is used for driving the detection unit to rotate; the interference unit is used for transmitting an interference signal to a target UAV; the main control unit is used for transmitting a detection control instruction to the detection unit, receiving the monitoring information transmitted by the detection unit, and recognizing the target UAV to perform target tracing; the main control unit receives the azimuth information of the cradle head unit, and transmits the cradle head control instruction to cradle head unit; and the main control unit transmits an interference instruction to the interference unit. The anti-UAV system is capable of effectively responding to threats from the UAV, and does not generate knock-on effects.
