摘要
介绍了双曲调频信号,其具有较大的时宽带宽积和良好的多普勒不变性,脉冲压缩之后基本不存在时频耦合问题。文中在理论分析的基础上,通过Matlab仿真,说明了HFM信号的脉压输出响应受多普勒频移的影响较小,在实际速度范围内能较好地获取目标的距离信息。
The thesis probes into hyperbolic frequency modulated （HFM） signal, which has large time-band- width product and good doppler invariance. And after pulse compression, it causes no problem of time frequency coupling. On the basis of theoretical analysis and with Matlab simulation, this paper indicates that compression output of HFM signal is little affected by Doppler shift and that it can better obtain the distance information of the target in actual speed range.
