It has been improved . multi - level recursive method include multi - level recursive identification , multi - level recursive prediction and multi - level recursive control 多层递阶方法包括多层递阶辨识、多层递阶预报和多层递阶控制。
According to the relationship of shannon ' s formula of boolean functions and bdd , the fault tree structure to bdd conversion was accomplished by recursive method 依据布尔函数shannon分解和bdd图的关系,用递归法实现了故障树向bdd转化。
Multi - level recursive method has been attached much weight since the eighties of the 20th century and was used in many fields such as petroleum , meteorology , finance , economy and so on 多层递阶方法自上世纪八十年代提出以来就引起了广泛的重视,应用于石油、经济、气象、金融、水利等领域。并在应用中不断的改进、完善。
The tree - based approach used for jibx code generation ends up constructing methods in this depth - first order anyway , so the duplicate checks work as long as there are no cycles in the method call graphs mutually recursive methods Jibx代码生成所使用的基于树的方法总能按照深度优先顺序构造方法;如果在方法调用图中没有循环(方法的相互调用) ,重复检查是有效的。
This paper analyses the numerical simulation problems of the semiconductor devices deeply . a one dimensional pn junction diode is worked out satisfyingly by the recursive method with the matlab5 . 3 software 论文深入的分析了半导体器件的数值模拟问题,利用matlab5 . 3等计算机工具,用解三对角矩阵方程的递归算法,实现了pn结二极管的一维求解,取得了比较满意的结果。
The natural line drawing is the one with hidden - parts - eliminated . based on the correlative constraints between vertices and straight lines on a planar object , we have proposed a new recursive method for computer interpretation of line drawings under orthographically axonometric projection 在建立了相关约束关系式的基础上,提出一种基于点与直线的相对位置关系递归解释线框图的新方法,主要针对的是正轴测投影线框图的计算机解释。
In chapter 3 , this paper recommended the methods of estimating the parameter of moving target using cyclostationary and analyzed the performance of this method firstly , and put forward a recursive method for estimating the parameter ( velocity , acceleration ) of moving target combining the characteristic of high - prf pulsed doppler radar . then , based on the resolution of doppler and acceleration , combining the characteristic of the doppler spectrun and acceleration spectrum , this paper put forward a new method for differentiating muli - target 然后,从弹载高重频脉冲多普勒雷达的多普勒分辨率和加速度分辨率出发,结合不同编队方式的多目标回波信号的特点,分析了多目标和单个目标的回波信号的多普勒谱和加速度谱的特性,提出了一种基于一维多普勒像和一维加速度像的级次多目标分辨算法。
Firstly , according to the characteristic that the doppler frequency shift signal can be approximated as a single sinusoid signal , the extended sinusoid signal retrieval ( pisarenko and esprit ) methods are presented and signal state and measurement formulations are developed , so the kalman filter recursive method is got . the brief introduction of low velocity moving target doppler frequency shift signal wigner - ville transformation and wavelet transformation expression are presented in this paper . secondly , because the clutter is gaussian distribution , cumement and high - order spectrum based methods are presented and the simulation results prove their good performance to suppress gaussian clutter in low velocity moving target doppler frequency shift signal processing 一个方面是根据低速目标的多普勒信号可简化为单一正弦波形式这一特点,得到了扩展的高斯色噪声背景下的谐波恢复算法,即高斯色噪声中的pisarenko谐波恢复法和旋转因子不变法( esprit ) ;并推导了信号的状态方程和观测方程,进而得到基于卡尔曼滤波的递推算法对信号进行提取;本文还简单的介绍了低速运动目标的多普勒频移信号的wigner - ville变换与小波变换;另一个方面是针对杂波服从高斯分布这一特点,提出了对接收信号求累积量和高阶谱来对高斯杂波进行抑制。
