摘要
介绍超宽带线性调频信号基带的数字产生方法及其实现技术。首先对线性调频信号的两种主要数字产生方法进行了简要阐述和比较,然后根据波形存储直读法提出了一种超宽带线性调频信号产生方案,分析了基带数字产生的主要关键技术,并进行了系统实现和测试。测试结果表明本文所提出的方法是可行的。
In this paper, the digital generation methods and the implementation techniques for Ultra wideband LFM baseband signals are introduced. The two main digital methods for LFM waveform generation are firstly narrated and compared, and a generation scheme for Ultra wideband LFM waveforms is presented according to the waveform storage method. Then,the key techniques in LFM baseband digital generation are discussed in detail. An experimental system has been implemented and tested. The results show that the scheme is feasible.
