In this thesis, we proposed a robust trilateration method to estimate Path Loss Exponent which stands for the signal attenuate rate for each reference node to target path by using two different frequency signals and the trilateration method. Then we used every PLE to calculate the corresponding distance and performed the trilateration positioning task using these distances. We also ran two simulations to evaluate our proposed method.

但另一方面，即使在同一空间中，却因为存在著许多变数而导致各个不同的路径都拥有自己的路径衰减指数，所以此篇论文我们提出先利用两个不同频率的讯号测得参考点到目标上的路径衰减指数后，再利用此数值做此路径的距离推导，最后再藉由三点定位法做出目标的定位。

The equal distance 3-improved-coverage number of beacon sending position is presented according the acreage of ROI.Then a simple method is put forward to calculate the coordinates of the sending positions in rectangular ROI.Aiming at the shortage of the existent sequence algorithm,when beacon moves according to the path and emits RF signals at every position,the ant colony algorithm is applied to the position sequence so as to get the beacon sending position.Further,in this algorithm the sensors could work out their position with trilateration.

根据ROI面积给出了等距三重优化覆盖此ROI所需要的信标发射位置数量计算方法；随后对矩形ROI提出了一种简单的信标发射位置确定方法；针对现有的遍历发射位置点的路径遍历算法的不足，提出了一种新的应用蚁群算法的信标发射位置点的遍历算法，并利用该算法对基于三边测量方法进行传感器节点定位。

分析结果表明剪刀式尾桨引起的气动噪声含有混沌特性，同时对比理论和试验结果表明剪刀尾桨构型的参数对气动噪声有明显的影响。

The time-history velocity response signal of pile can be decomposed by Sym wavelet. The power spectrum value can be extracted from some specified spectrum range. These values from one signal makes up the characteristic vector representing this signal. The relationship between characteristic vector of pile and pile defect type can he established by using BP artificial neural network. Abundant time-history velocity response signals of pile can be acquired by numerical simulation method.

利用Sym小波对基桩速度响应时程曲线进行小波分解，对指定频带上的信号分量进行特征值提取，提取的特征值为反映各频带范围内体现能量分布的功率谱均值，提取的特征值可构成反映信号特征的特征向量，同时利用BP人工神经网络的非线性映射特性建立特征向量和基桩缺陷类别之间的一种对应关系。
