摘要
根据雷达自动增益控制的原理,讨论在单脉冲跟踪雷达中数字AGC技术的工作原理及实现方法,重点介绍使用数控衰减器在数字中频接收系统中,实现自动增益控制的方法,较详细论述数控衰减器AT107在某型号跟踪雷达接收机数字增益控制电路中的应用,给出了具体应用电路,在实际使用中使得雷达DAGC系统参数调整灵活,提高了可靠性,同时实现电路板的小型化。
The principle and method using digital attenuators in digital AGC in the application of monopulse tracking radar with the prinicple of AGC techology for radar are discussed. It presents AGC method in digital IF receiving system,and gives a typical application and the electronic scheme in DAGC of a radar with model ATI07 digital attenuator. In the pratice, the reliablity is improved and making easy tuning in DAGC while miniaturized the electronic boards.
