本文主要讨论在具有脉压和动目标显示的雷达系统中,当定时触发不稳时,脉压中展宽信号的不同实现方案对动目标显示性能的影响。重点是比较sinx/x信号产生的两种方法:平衡调制法和窄脉冲冲击法;分析表明前者优于后者。
In this paper, we mainly discuss the effect of different implementations of signal broadening in pulse pressure on the moving target display performance when the timing triggering is unstable in a radar system with pulse pressure and moving target display. The emphasis is on comparing two methods of sinx / x signal generation: the balanced modulation method and the narrow-pulse impact method; analysis shows that the former is superior to the latter.
