寄存器版读正交编码器的值，测试成功 。。。。。。。。。。(encoder.c test)

可将实测河道断面转化为梯形断面，用于平原河网水动力学计算。(The measured channel section can be transformed into a trapezoidal section)

说明：  光栅法三维重建时设置不同频率生成4步相移图片，图片大小为768*1024(Raster 3d reconstruction generates 4 - step phase shift images)

说明：  复杂环境中的微弱目标（如隐身飞机、被地/海/城市杂波淹没的目标等）探测 问题是现代雷达面临的严峻挑战。 与传统的先检测后跟踪（ DBT） 技术相比， 检 测前跟踪（TBD）技术是一种新兴的先进信号处理技术，它通过多帧回波数据积 累和联合处理，可以显著提高雷达的微弱目标检测跟踪性能， 是国际雷达界研究 的前沿热点。 TBD 作为一项正在发展中的新技术，还需要解决一些新的技术问题， 例如， 多目标跟踪维数灾难、临近目标相互干扰等，以及处理难度增加和运算量 增大带来的新问题。(The detection and tracking of low observable targets (e.g. stealth targets, targets buried in strong clutter) in complex environment are great challenges for modern radar systems. Different from the traditional detect-before-track (DBT) methods, Track-before-detect (TBD) is a novel and efficient signal processing method which is proposed in recent years to detect low observable targets, and has got much attention internationally in radar research area. By jointly processing several data frames, TBD is able to produce more reliable detection and tracking results. As a developing new technique, TBD has its own problems and challenges. For example, existing studies on)
