文章分析了末制导雷达接收机和差通道幅相不平衡对角度误差信号测量的影响,提出了一种数字和差通道幅相失衡校正方法并利用FPGA(Field Programmable Gate Array,现场可编程逻辑阵列)进行了硬件实现。测试结果表明设计的校正系统校正精度高、校正速度快。该校正系统硬件资源消耗小,且不改变雷达接收机系统结构。
The article analyzes the influence of the terminal guidance radar receiver and the differential channel amplitude and phase imbalance on the measurement of the angular error signal, proposes a digital and differential channel amplitude and phase imbalance correction method and uses FPGA (Field Programmable Gate Array, Field Programmable Logic Array ) For the hardware implementation. The test results show that the calibration system designed has high calibration accuracy and fast calibration speed. The calibration system hardware resource consumption is small, and does not change the radar receiver system structure.
