摘要
多种调频信号的组合是低截获概率(LPI)雷达技术的发展方向。在比较了多种非线性调频信号脉压性能的基础上,提出了一种基于AD9958型直接式数字合成(DDS)的LPI雷达多波形设计,并采用数字线性逼近法实现了非线性调频信号的方法。
The combination of multi-signal is one of the important aspects of the low probability of intercept （LPI）radar technology.Compared the pulse compression performance of many non-linear FM signals,a design of multi-signal for LPI radar based on the direct digital synthesizer（DDS）AD9958 is presented in this paper. The system uses the NLFM method to realize digital linear approximation signals.
