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. )

说明：  PWM整流器仿真，稳压效果好，采用svpwm调整，pll锁相环并网，电流波形纹波小，响应快(Simulation of PWM rectifier shows that the effect of voltage stabilization is good, SVPWM adjustment is adopted, PLL phase-locked loop is connected to the grid, the current waveform ripple is small and the response is fast)

应用背景isodata聚类算法可以通过类的自动合并与分裂，得到较为合理的类型数目c。它的聚类效果相比于c-均值算法而言具有更好的聚类效果，实现过程更为复杂。适用于聚类各种场合。关键技术 isodata聚类算法中，起始聚合中心的选取对聚类过程和结果都有较大的影响，如果选择的好，则算法的收敛速度快，聚类质量高。相比较于c-均值算法而言，c-均值算法简单，isodata算法复杂，isodata算法的类型数目可变。
