Description: Divides the range swath (range cells) of this block into Nspect sections
and finds the average power spectrum for each segment.
Fits a parabola to the baseband Doppler centroid vs. range
This fit is most useful if the whole range swath is selected, but the
computing times get large if more than 1024 range lines (azimuth cells)-Divides the range swath (range cells) of this block into Nspect sections

Description: 从回波中估计多普勒参数是合成孔径雷达运动补偿的关键。文中研究了多目标回波对参数估计的影响，从理论上推导了估计多普勒中心和调频率对回波的不同要求，并用两个指标举例分析了一段实测机载SAR数据，给出了实际应用中参数估计时选择回波的原则。-Doppler parameters estimation from radar echoes is a key step in SAR(Synthetic Aperture Radar}motion cornpensation．
This paper researched the efect of multiple targets echoes to estimate parameters and deducted theoretically the different
requirement for echoes in estimating doppler centroid and doppler frequency modulation rate．Th en giving a real airborne SAR echo
as example，we analyzed it with two measurements and concluded the principle about choosing echoes in practice． Platform: |

Description: this function is estimate doppler centroid in synthetic aperture radar with ACCC.The basic SAR theory is conceptually simple yet when one looks into the inner workings of the
SAR processor it appears quite complicated(The most difficult part of the problem is related to
the coupling between the azimuthal compression and the orbital parameters. In the old days
when the satellite orbits were not known very accurately, one would use techniques such as
clutterlock and autofocus to derive the orbital parameters from the data) Platform: |
