Research on the Digitization of Fire Control Radar's Angle Information

介绍基于正切式算法的火控雷达天线角度信息的数字化方案。方案采用了峰值采样和查表求角,给出了其设计原理及软硬件实现方法。雷达实验证明该方案稳定、可靠,精度较高,成本较低,有利于推广应用于各种旋转变压器接口的轴角测量系统。

A solution to digitize the antenna＇s angle information of the fire control radar based on tangent algorithm is proposed in this paper. To avoid overflow and improve precision, sampling at the signal peak and two tables are adopted. The principle is analyzed and the configuration of software and hardware is presented. The experiments show that the solution is steady, reliable, high-accuracy, and low-cost. It can also be applied to various kinds of angle measuring systems based on resolvers.
