本文介绍一种采用小型计算机或微机控制的雷达中频信号模拟器。它是将计算机产生的全部模拟参数的数字量转换为相应的模拟量。该模拟系统具有高逼真度和灵活性,仅对软件做相应的改变就可以模拟不同运动特性的目标,它已成为现代雷达进行系统试验,功能检查和培养操作人员不可缺少的设备。 This article describes a small computer or computer-controlled radar IF signal simulator. It is the computer generated all the analog parameters of the digital conversion to the corresponding analog. The simulation system with high fidelity and flexibility, only the software to make the appropriate changes to simulate the different objectives of the movement, it has become a modern radar system testing, function checking and training of operators indispensable equipment.
