2 . the signal correlation spectrum is corrected to rectangle spectrum by using spectrum correcting technique and then added window to restrain distance sidelobe , and all one dimension divided correlation outs are added diversified windows to restrain rate sidelobe
2 、利用谱修正技术把相关输出信号频谱修正成矩形频谱，再加窗抑制距离旁瓣，对所有一维分段相关输出组纵向加各种窗形抑制速度旁瓣。
However , when the input noise is the double - peak gaussian mixture noise , the noise can improve the signal correlation for the subthreshold signal and the suprathreshold signal , i . e . , both sr and suprathreshold stochastic resonance ( ssr ) often occurs
而当输入噪声为双峰高斯混合噪声时，不仅输入信号在阈下时随机谐振现象有时存在，而且输入信号在阈上时噪声往往也能改善信号的相关性，即阈上随机谐振现象存在。
In the second part , the new method is compared with the old one in such aspects as system structure and signal processing methods . in the third part , the properties of dsss and lfm systems , especially the echo signal correlation processing of the systems are discussed . the last part are the respective analyses of water - pipe simulation experiment results and the trial results in zhong yuan oil field
本文首先介绍了超声测距的基本原理，分析了信道的声传输特性；接着将传统液位测量方法和新型液位测量方法的系统构成和信号分析处理方法做比较；然后对系统的发射信号(直接序列扩频信号和线性调频信号)的特点进行了研究，并着重讨论了回波信号的相关处理；最后对水管模拟实验测量结果和油田实地测量结果分别进行了分析和讨论。
Frequency code is not uniformity distribution and keeps to a probability distribution function defined by the spectral characteristics of the target of interest . the phase code is equally duality pseudo - random sequence and used to reduced the sidelobes of the signal correlation function . and the mismatch - phase sequence is corresponding with the frequency sequence one by one
而频率编码为不均匀分布，由所观测目标的频谱信息提取出概率密度函数决定频率编码序列的分布；相位编码为二元的伪随机序列，采取均匀的二相编码，消减同频脉冲带来的过高的相关函数的旁瓣；而失配相位为与频率编码相一一对应于各子脉冲中。
