建立发射波束零陷形成模型,运用泰勒展开对零陷形成模型线性化,通过计算控制置零方向的辐射增益来确定天线权值,提出了一种快速的发射波束宽零陷形成方法。并通过对ARM导弹攻击时异地测量、角度解算、误差补偿、ARM导弹机动补偿,讨论了影响ARM导弹威胁角度计算的主要因素,通过合理近似,计算出ARM导弹攻击的威胁角度区域,研究了发射波束宽限形成技术在制导雷达在抗ARM导弹攻击中的应用。

With the set-up of null transmit beamforming model and the linearization of the transmit model with Taylor expansion, a fast wide null transmit beamforming technology is presented in this paper. Through separate measurement of the ARM＇s assault, angle solution, error compensation, ARM maneuvering compensation, the main factors affecting the calculation of threat angle area of ARM attack. With reasonable approximation, the threat angle area of ARM attack is worked out. The application of the wide null transmit beamforming technology for the radar in anti-ARM battle is studied.
