一、前言众所周知,入射波在遇到雷达制导导弹导引头的天线罩时会发生折射。不同的入射角,将会有不同的折射角。导引头接收到的目标信息,实际上是经过折射后所产生的一个虚像。我们称前者为真实目标视线,后者为视在目标视线,二者之差,称为瞄准误差。通常瞄准误差被认为是视在目标视线角的线性函数,其斜率R称之为雷达天线罩的误差折射斜率。瞄准误差的出现,对于雷达寻的导弹制 I. INTRODUCTION As we all know, the incident wave will be refracted when it encounters the radome of radars guided missile seeker. Different angles of incidence will have different angles of refraction. Seeker receives the target information, in fact, is a virtual image after refraction. We call the former the line of sight of the real target, the latter of the line of sight of the target of sight, the difference between the two, called the aiming error. The usual aiming error is considered as a linear function of the apparent target viewing angle, the slope R of which is referred to as the error refractive slope of the radome. Aiming for the emergence of errors for the radar to find the missile system
