Data and code underlying Ch. 7 of PhD thesis: Phased microphone array noise measurements of a Cessna Skymaster at Teuge International Airport

The goal of the measurements is to understand the noise sources on propeller aircraft in various conditions, during flyovers and engine runups.<br>The flyover measurements were conducted with a phased microphone array consisting of 64 channels for an aircraft from DEAC. The pilots were performing low-passes in various airframe configurations at Teuge International Airport, The Netherlands. During these measurements additional data on aircraft performance, e.g. engine data, as well as from a GPS tracker has been saved. For this, the processed data has been shared with the spectra at overhead position.<br>The data set also includes microphone array measurements (112-mics) of engine runups at various positions around the propeller plane. A code is provided to read the time-pressure data and allocate the data to a microphone coordinate, such that acoustic imaging methods can be applied.

本测量的核心目标为探究不同工况下，螺旋桨飞机在通场飞行与发动机试车过程中的噪声源。
本次通场飞行测量采用了由64个通道组成的相控麦克风阵列（phased microphone array），测试对象为DEAC公司的一架螺旋桨飞机。试飞员在荷兰特赫国际机场，针对不同机身构型开展低空通场作业。本次测量过程中，同时采集并存储了飞机性能相关的附加数据（如发动机数据）以及GPS追踪数据。经处理后的数据集已同步附带飞越头顶时刻的频谱数据。
本数据集还包含针对该螺旋桨飞机周边不同位置开展的发动机试车麦克风阵列测量（共112个麦克风）。数据集附带了配套代码，可用于读取时压数据（time-pressure data）并将其匹配至对应麦克风坐标，以便开展声学成像相关研究。
