介绍了什么是电子干扰，干扰的种类；以及抑制干扰的优秀手段--自适应波束形成；
Interference or electromagnetic interference(EMI) is disturbance that
affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source. The
disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the circuit. These effects can range from a simple degradation of data to a total loss of data. The source may be any object, artificial or natural,that carries rapidly changing electrical currents, such as an electrical circuit, the
Sun or the Northern Lights.
