Description: 在分析聚束合成孔径雷j盘(SAR)方位向时频关系的基础上，提出了一种新的全孔径分辨率SAR成像算法。
根据SAR在条带与聚束模式下回波信号之间的差别，利用现有成熟的条带SAR成像算法实现先对聚束SAR各方位向子
孔径成像，而后再将各方位子孔径带宽合成为全孔径带宽，以形成具有全孔径分辨率的SAR图像，极大降低了系统PRF
的要求。-In the analysis of spotlight synthetic aperture radar dish j (SAR) azimuth based on the time-frequency relationship, a new full-aperture resolution SAR imaging algorithm. According to SAR in strip and spotlight mode, the difference between the echo signal, the use of existing mature band SAR imaging algorithm first bit of the spotlight SAR the parties to the sub-aperture imaging, and then place then all the bandwidth synthetic aperture the bandwidth for the full aperture to form a full aperture resolution SAR images, greatly reducing the system PRF requirements.

Description: The Phase Gradient Autofocus (PGA) algorithm
has been widely used in Spotlight Synthetic Aperture
Radar (SAR) to remove motion-induced blurs in the
images. The PGA algorithm has been proven to be a superior
autofocus method. PGA assumes a narrow beam,
which is valid for most SAR systems. However, lower altitude
SA& have large range dependencies that cannot be
ignored. A new phase estimator for PGA is introduced
and extended to allow range dependence. An ERS-1 image
of Death Valley is used in simulations comparing the
new estimator to the widely used maximum likelihood approach
and in demonstrating the range-dependent PGA
algorithm.

Description: Phase-Gradient autofocus (PGA) technique is
robust over a wide range of imagery and phase error
functions but the convergence usually requires 4-6
iterations. In this paper, we propose to speed up the
estimation convergence by selectively increasing the pool of
quality synchronisation sources and not to be limited by the
range pixels of the SAR map. This is highly probable since
each range bin contains more than 1 prominent scatterers
across the integration aperture. It is also highly probable
that the least brightest selected scatterer in a range gate may
turn out to be of higher energy as compared to the
maximum brightest scatterer of another gate. With
appropriate target filtering to final select the quality
scatterers out of the large pool and higher-order phase error
measurement tool, the new algorithm achieves near
convergence quality without iteration. We named this
solution the Quality PGA algorithm (QPGA).

Description: 滑动聚束模式的RD成像。聚束模式SAR中,天线始终指向场景中心,合成孔径的长度比相同条件下的条带式SAR长。对于滑动聚束模式SAR系统,由于天线的指向变化与两者都不同,所以与条带模式相比,其合成孔径更长,而且测绘带区域比聚束模式更大
-The Sliding Spotlight model described in the article can geta better resolution than strip-map mode and better observed area than spotlight mode.by steering the antenna on a point further away the radar than the area beingilluminated which can be regarded as coming the underground. By doing this, thismode can get good combination between the resolution and observed area.
