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. )

该算法具有聚类速度快、聚类结果可读性好、聚类准确度高等优点，非常适用于高效的网页在线聚类。 (The clustering algorithm is fast and good readability clustering results, clustering high accuracy, very applicable to high-performance clustering of web pages online.)

LDPC码既低密度奇偶校验码（Low Density Parity Check Code，LDPC），它由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码，不仅有逼近Shannon限的良好性能，而且译码复杂度较低, 结构灵活，是近年信道编码领域的研究热点，目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。LDPC码已成为第四代通信系统(4G) (LDPC codes BER simulation under AWGN channel. MacKay-Neal based LDPC matrix. Message encoding uses sparse LU decomposition. There are 4 choices of decoder: hard-decision/bit-flip decoder, probability-domain SPA decoder, log-domain SPA decoder, and simplified log-domain SPA decoder.)
