The invention belongs to the technical field of electromagnetic signal interference checking, and particularly relates to an electromagnetic signal interference checking system and interference checking method for a coaxial rotor wing capable of being folded in a cylindrical mode. According to the electromagnetic signal interference checking system, the coaxial rotor unmanned aerial vehicle is adopted to carry the foldable direction-finding antenna array, the whole aerial part can be folded, can be accommodated in the launching cylinder after being folded, can be launched by the launching cylinder, is convenient to carry and can be quickly unfolded, and the application in special occasions such as in-vehicle launching or aerial delivery of an aerial carrier is met; a coaxial rotor unmanned aerial vehicle is selected to carry a multi-antenna monitoring direction-finding load, the coaxial rotor unmanned aerial vehicle flies in an inclined propeller disc mode, compared with a multi-rotor unmanned aerial vehicle, the attitude change is small during flight, the influence on the attitude of an antenna array is small, and continuous direction finding of the unmanned aerial vehicle on an electromagnetic target during flight can be achieved; and the antenna control mechanism is arranged, so that the antenna array spacing can be adaptively adjusted in the air according to the required frequency range, the direction-finding frequency range of the system is expanded, the fuzzy problem is avoided, and the working efficiency of the system is improved.

    本发明属于电磁信号干扰排查技术领域,具体涉及可筒射折叠的共轴旋翼电磁信号干扰排查系统及干扰排查方法。该电磁信号干扰排查系统,采用共轴旋翼无人机搭载可折叠测向天线阵,空中部分整体可折叠,折叠后可容纳于发射筒中,可由发射筒发射,方便携带和快速展开,满足于车内发射或者载机空投等特殊场合应用;且选用共轴旋翼无人机搭载多天线监测测向载荷,共轴旋翼无人机采用倾斜桨盘的方式飞行,相比于多旋翼无人机,飞行时姿态变化小,对天线阵姿态影响小,能够实现无人机在飞行中对电磁目标的持续测向;且具备天线操纵机构,能够根据所需频率范围,在空中自适应调整天线阵间距,扩展系统测向频率范围,避免模糊问题,提升系统工作效率。
