摘　　要：分析了雷达的自动增益控制的原理,提出了一种适用于脉冲雷达的数字化AGC的设计与实现方案,对于数字AGC的控制模块及电压与功率在不同输入条件下的关系进行了详细的介绍,在FPGA的软件设计及实现算法的基础上,通过线性调频信号雷达系统进行验证,试验结果表明方案具有收敛速度快、控制精度高等特点。A kind of design and implementation of digital automatic gain control（ DAGC） with pulse radar is proposed after researching the principle of AGC,digital automatic gain control module,and the relationship between voltage and power under different input conditions are mainly introduced. On the basis of FPGA software design and implementation of algorithms,validation of algorithms is verified based on radar system of linear frequency modulated（ LFM） signal. The results indicate this digital automatic gain control is fast-convergence and high-precision.
