When a bird or an insect such as a cricket or grasshopper chirps, it makes short, high-pitched sounds.
Chirp is also a noun.
chirping

啁啾
Notably, in our derivations, the effect of chirp fluctuations has been critically taken into account as well as the dispersive and nonlinear effects.
值得注意的是,在我们的推导过程中,啁啾波动效应连同色散和非线性效应均得到充分的考虑。
线性调频
In ideal circumstances, the back scattered echo signal of SAR is chirp signal. With synthetic aperture theory, high azimuth resolution imaging to distant targets can be attained.
理想情况下，SAR回波多普勒信号是线性调频信号，采用合成孔径原理提高方位向成像分辨率。
脉间步进跳频
There are several ways to achieve high range resolution. In this dissertation ,not only the theory analysis ,but also engineering application study of both a stepped frequency and an intra-pulse chirp and inter-pulse stepped frequency are completed.
利用合成宽带技术来实现距离维的高分辨可以有多种方式,本文着重探讨了步进跳频及脉内调频、脉间步进跳频技术的理论分析和实现研究。
