摘　　要：现代舰载搜索雷达使用线性调频信号以增大搜索范围和提高测距精度,而反辐射导弹(ARM)比较相位测角系统对线性调频信号存在测量偏差,文中推导了线性调频信号与比较相位测角偏差的关系,在考虑海面镜像反射的情况下,推导了反辐射导弹打击海面线性调频雷达瞄准点偏移和散布公式,在典型弹道上仿真计算瞄准点散布数据,为海上使用反辐射导弹提供理论依据。Modern ship-borne searching radar uses linear frequency modulated signal to increase searching range and accuracy,but anti-radiation missile＇s phase comparison direction measurement will get an angle bias when it deals with this kind of signal. In this paper,the direction measurement result influenced by linear frequency modulated radar signal was analyzed,the bias and its aiming spread calculation method considering mirror reflection were deduced. Based on a typical trajectory,the bias spread variances were calculated at different distances. The analysis results of this paper give a theoretical calculation method for ARM＇s attacking sea surface target.
