摘　　要：文章分析了气球载雷达的功能,指出气球载雷达由于载体特性,需要根据气球姿态对雷达目标进行实时修正。利用FPGA实现流水线结构的CORDIC算法能够对气球姿态传感器回送数据进行实时解算,占用资源少,综合频率高达100 MHz,通过仿真可以看出,综合结果完全能够适应高速实时处理的要求。Based on the analysis of the function of aerostat radar,this paper points out that real-time processing of radar target based on tethered aerostat pose is needed in view of the load peculiarity of aerostat radar.By using FPGA to realize the pipeline CORDIC algorithm,the data received from aerostat pose sensor can be computed in real time.The FPGA occupies few resources,but synthesis frequency can be up to 100 MHz.The simulation result shows that the synthesis can meet the demand in high speed occasion.
