摘要
描述了机载火控雷达中用于连续波制导导弹测试及调谐的多普勒模拟器的实现方法,给出使用数字合成技 术取代传统模拟方式所产生的效果,对使用数字合成设计与模拟设计方案在频率精度、信号稳定度和谐波抑制等方面的 性能进行了比较,从而得出数字合成方案不仅设计合理且能够显著提高系统性能的结论。由于数字合成方案采用大规模 集成电路和可编程器件,还有利于实现批生产,提高了工作效率。
The realization methods of a Doppler simulator which is employed in an airborne fire-control radar for CW guided missile testing and tuning are described in this article. The effects of replacing traditional analog method with digital synthesis technology are given. Then a reasonable scheme for digital synthesis obtained from the performance comparison of frequency precision、stability and harmonic suppression. The digital synthesis technology can also increase work efficiency and be useful for batch production because of application of large scale integrated circuits and programmable components.
