本文描述了TA—10雷达MTI系统的工作原理,分析了回波为强信号和弱信号时的系统传输特性。讨论了各个门限的选择原则。TA—10雷达MTI系统的主要特点是,对于强信号具有理想矩形的频率响应,因而在强杂波背景中,对各种多普勒频率的运动目标改善作用均匀;其次,它的独特的弱信号处理方法可将杂波剩余保持在噪声电平的水平上。 This paper describes the working principle of the TA-10 radar MTI system and analyzes the system transmission characteristics when the echo is strong signal and weak signal. The principle of choosing each threshold is discussed. The main feature of the TA-10 radar MTI system is that it has an ideal rectangular frequency response for strong signals and therefore has a uniform effect on moving targets of various Doppler frequencies in a strong clutter background. Second, its unique weakness The signal processing method keeps the clutter residual at the noise level level.
