Doppler centric frequency is influenced much greater than Doppler FM rate and azimuth resolution is.
对多普勒中心频率影响大,对多普勒调频斜率及方位分辨率影响小。
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。
The very strong property of the synthetic array sonar is the ability to acquire a high azimuth resolution from a physically small array.
