摘　　要：针对常见的雷达有源欺骗式干扰——距离欺骗假目标干扰,提出了一种阵列雷达发射时采用频率分集阵列(FDA)模式,接收时采用常规相控阵模式的假目标鉴别方法。雷达选定需要鉴别的目标,利用FDA发射方向图距离角度二维相关的特点,使方向图主瓣经过需鉴别目标而不经过其他目标,根据接收到信号的不同鉴别出目标的类型。通过计算机仿真表明了所提方法具有良好的目标鉴别效果。A method for array radar to suppress a common radar active deception jamming-range deception false target jamming is proposed. This method is that radar adopts frequency diverse array( FDA) mode on transmitting and conventional phased array mode on receiving. Radar selects the target which needs to be identified and makes the mainlobe of transmitting antenna pattern pass it without passing other targets because FDA’ s pattern is two-dimensional correlation in distance and angle. Different targets produce different kinds of echo and radar judges the nature of the target according to its echo. The results of computer simulation demonstrates that this method has a great effect on identifying target.
