摘要
文章论述了一种适合多种雷达的灵敏度时间控制技术。根据目标的回波电压随距离二次方变化的特性，采用控制特性存贮技术，实时控制大动态中频放大器，解决了由于雷达目标随距离变化引起的回波信号变化问题。它控制灵敏、范围大、精度高，进一步提高了雷达的整机性能。
This paper deals with a kind of sensitivity time control technique,which suits many kinds of radar.According to the property that the echo signal voltage varies with the square of the distance from the target,the technique of the control property storage is adopted so as to make the real time control of the intermediate frequency amplifier with a large dynamic range.which has solved the problem of the echo signals variation with the distance of the radar targets.This technique has the advantages of sensitive control performance,a large dynamic range and a high accuracy.It has improved the overall performance of the radar.
