摘　　要：由于宽频段雷达制导中的雷达头对工作频率较低以及高频点的检测信噪比较低,并且检测噪声受到雷达频点和地形等因素的干扰,使得传统鲁棒滤波的制导模型,无法处理高随机性的噪声,不能实现雷达制导的高精度引导。提出一种基于惯导系统的雷达制导高精度引导模型,采用惯导位置、速度信息辅助抗舷外干扰的信息操作方法,在宽频段雷达制导跟踪过程,塑造弹目相对运动模型,采用扩展卡尔曼滤波降低雷达引导头随机检测误差,得到目标位置以及速度信息,实现导弹制导的高精度引导。实验结果说明,所提方法具有较高的引导精度和鲁棒性,是一种有效的雷达制导引导模型。Since radar heads in wideband radar guidance have a low working frequency and low signal noise ratio（SNR） for the detection of the nodes of high frequency,and the detection for noise is interfered by factors,like radar frequency nodes and topography,which makes the traditional guidance model of robust filtering unable to achieve high precision for guidance of radar. A radar guidance precision guide model was proposed based on inertial navigation system the. The inertial navigation position and velocity information were adopted to assist information operation method of anti-outboard interference. During the process of wideband radar guidance tracking process,relative motion model for bullets was built,and extended Kalman filtering was utilized to reduce random detection error of the radar seeker,so as to obtain target position and velocity information,and realize the high precision for missile guidance. The experimental results indicate that the proposed method has higher guidance precision and robustness,and is an effective radar guidance model.
