复杂电磁环境信号采集和回放试验数据集

复杂电磁环境信号采集和回放试验数据库涵盖信号采集录制、预处理、校场和回放监测四个核心部分的数据内容。采集录制阶段包括原始信号（频域数据）、采集参数（带宽、中心频率、信号大小）及环境信息；预处理阶段涉及降噪分选后的信号、特征提取数据（调制参数、统计特征）及标注信息；校场部分包含设备校准数据、参考信号库及环境验证结果；回放监测则记录重构信号、异常日志。此外，试验配置、中间数据处理和安全管理信息等辅助数据贯穿全程，形成多维度、结构化的电磁信号数据库，支撑信号分析、设备验证及算法开发。

This Complex Electromagnetic Environment Signal Acquisition and Playback Test Database encompasses data from four core modules: signal acquisition and recording, preprocessing, calibration stage, and playback monitoring. The acquisition and recording phase includes raw signals (frequency-domain data), acquisition parameters (bandwidth, center frequency, signal amplitude) and environmental information. The preprocessing phase covers denoised and sorted signals, feature extraction data (modulation parameters, statistical features) and annotation information. The calibration stage section includes equipment calibration data, reference signal repositories and environmental validation results. The playback monitoring module records reconstructed signals and anomaly logs. In addition, auxiliary data such as test configuration, intermediate data processing workflows and safety management information runs through the entire lifecycle of the database, forming a multi-dimensional and structured electromagnetic signal database that supports signal analysis, equipment verification and algorithm development.
