摘要
较详细地介绍了一种LFM信号频带扩展和搬移的设计,该系统实现了300MHz超宽带线性调频,并具有优良的线性相频特性、带内平坦度和低杂波性能。文中给出了研制结果。
A design of widening and moving of LFM signal band is presented in this paper. Using this design,a system is realized which has 300MHz ultrawide-band LFM signal with good linear phase-frequency characteristic, smoothness within band and low spurious signal. Some results of experiments are given.
