摘要
圆锥扫描体制由于其简单、体积小且成本低,较广应用于毫米波雷达导引头。文中提出了一种用于锥扫脉冲多普勒雷达导引头的测角算法-傅氏变换法,可以应用于多圈锥扫数据提取目标角误差。通过误差分析,对算法进行了进一步修正,算法仿真验证了其有效性及高精度性能。
Conical scan technique is widely used for radar seekers because of its simplicity, low cost and small size at millimeter wavelengths. In this paper a method of obtaining target angle error for conical scan MMW pulse doppler radar seeker is presented. It is based on Fourier transform and can use multiple circle data of conical scan radar to obtain the angle error of the target. Then the algorithm error is analyzed and the algorithm is modified. The simulation results validate its feasibility and high precision.
