摘　　要：对基于真对数放大器的雷达中频接收机进行了原理分析和数学分析,并给出了一个基于真对数放大器的雷达中频接收机实例。利用仿真程序,建立了基于真对数放大器的雷达中频接收机数学模型,并对其抗干扰能力进行了仿真评估,验证了采用基于真对数放大器的雷达中频接收机可以提高雷达的抗干扰能力。The work principles of radar IF receiver which based on true logarithmic amplifier are analysed. The design of radar IF receiver based on true logarithmic amplifier is introduced. By simulating program, it establishes math module of radar IF receiver which based on true logarithmic amplifier, given simulate evaluation for the receiver＇s anti-interfere ability. It is validated that radar IF receiver which based on true logarithmic amplifier can advance the anti-interfere ability of radar.
