Small ultra-short-wave automatic jammer

The utility model relates to a small ultra-short-wave automatic jammer which belongs to the technical field of communication countermeasure and is used for autonomously reconnoitering and jamming communication signals in an ultra-short-wave frequency range. The small ultra-short-wave automatic jammer comprises a control terminal, a reconnaissance and jamming host and an antenna, wherein the control terminal sets working parameters and binds the working parameters into the reconnaissance and jamming host, the reconnaissance and jamming host automatically loads the working parameters and starts reconnaissance and jamming, and the reconnaissance and jamming host receives a target communication signal through the antenna, completes detection, generates a corresponding interference signal and sends the interference signal out through the antenna. The small ultra-short-wave automatic jammer has the following advantages: the jammer is simple to operate, can work once being turned on and does not require manual duty;
