摘要
本文从提高现代成像雷达距离维分辨率和发现能力的角度讨论了大时宽、带宽信号在雷达信号波形设计中的重要性，以及获得大时宽、带宽信号的方法。文中不仅给出了宽带线性调频（ＬＦＭ）信号的具体设计方法，而且给出了可产生多种复杂波形的实验信号产生系统及其主要技术指标。文章的最后给出了产生时宽２３μｓ、调频带宽７０ＭＨｚ、中频２２０ＭＨｚ线性调频信号时的主要测试结果。
This paper discusses the importance of large time bandwidth product signals in radar signal waveform design and the methods of its generation,which are useful to improve resolution and identification probability in modern imaging radars.A method of designing linear frequency modulated(LFM) signals with wide bandwidth and an experimental system that can generate many complex waveforms are presented.With this system,the LFM signal whose basic parameters are the time width of 23μs,FM bandwidth of 70MHz and immediate frequency of 220MHz is generated.Some test results are presented.
