直接序列扩频（Direct Sequence Spread Spectrum）工作方式，简称直扩方式（DS方式）。就是用高速率的扩频序列在发射端扩展信号的频谱，而在接收端用相同的扩频码序列进行解扩，把展开的扩频信号还原成原来的信号。(irect Sequence Spread Spectrum (Direct Sequence Spread Spectrum), hereinafter referred to as Direct expansion mode (DS). Is a high rate of spread spectrum sequence extension in signal spectrum, and at the receiving end with the same spread spectrum code sequence for expansion, the expansion of the spread spectrum signal back into the original signal. )

说明：  包含雷达信号处理的基本流程与操作规范的matlab代码示例，内容选摘如下： 一、脉冲压缩 窄带（或某些中等带宽）的匹配滤波： 相关处理，用FFT数字化执行，即快速卷积处理，可以在基带实现（脉冲压缩） 快速卷积，频域的匹配滤波 脉宽越小，带宽越宽，距离分辨率越高； 脉宽越大，带宽越窄，雷达能量越小，探测距离越近；(Matlab code examples including the basic flow and operation specifications of radar signal processing are as follows:)

介绍了一种基于 MA T L A B的多个特定人连接词语音识别的方法，并提出了在进行端点检测时，引入平均的概念能进一 步提高识别率。 此设计是以 L P C C系数、 D T W 算法为核心的基于图形界面的设计。 通过大量的实验测试 ，表明该方法基本达 到屏蔽外界环境的影响 ， 具有非常高的精度识别(: In this paper based on a number of specific persons MA TLAB conjunctions speech recognition method, and presented during endpoint detection, the introduction of the concept of the average recognition rate can be further improved. This design is LPCC coefficients, DTW algorithm as the core design based on graphical interface. Through a large number of experimental tests show that the method is basically to shield the external environment, with very high accuracy recognition)

说明：  RD算法作为SAR处理中最重要的处理算法，在远场近似的条件下，可将二维处理分离为两个一维处理，降低了运算量，成像效果良好。(RD算法作为SAR处理中最重要的处理算法，在远场近似的条件下，可将二维处理分离为两个一维处理，降低了运算量，成像效果良好。 RD algorithm is the most important processing algorithm in processing SAR, in the far field approximation, the two-dimensional separation into two one-dimensional processing, reduces the amount of computation, good imaging effect. )
