摘　　要：针对雷达发射信号时采用频控阵模式、接收信号时采用相控阵模式的抗主瓣欺骗干扰方法,研究了一种干扰置零方法,在频控阵发射方向图的主瓣对准需鉴别目标的位置时,使其他目标位于方向图的零陷处,解决了在使用频控阵进行目标鉴别时其他位置处目标若位于频控阵方向图较高旁瓣上时仍能对雷达形成干扰的问题。计算机仿真结果证明了所使用的干扰置零方法具有可行性和有效性。The anti-main lobe deceptive jamming method enables the radar to adopt the frequency diverse array(FDA)mode during signal transmitting and the phased array(PA)mode during signal receiving.In view of this,a jamming nulling method is studied in this paper.When the main lobe of the transmitting antenna pattern of the FDA is aligned with the position of the target to be identified,other targets are located at the nulls of the pattern.As a result,the problem of interference on radar can be solved when the target is located on the higher sidelobe of the array pattern in the case that the FDA is used for target identification.The computer simulation results prove that the jamming nulling method used in this paper is feasible and effective.
