TFCat（时频目录）是一种基于JSON（JavaScript Object Notation）的数据交换格式，最初设计用于交换低频无线电事件和特征。它定义了几种类型的JSON对象，以及如何将它们组合起来表示与时间谱图的时间谱特征相关的数据（也称为，动态频谱），它们的属性，以及它们的时间和频谱范围。此实现继承自GeoJSON文件格式。TFCat python库实现了该规范，并提供了一个软件接口，允许有效地创建，更新和验证TFCat对象。
TFCat (Time-Frequency Catalogue) is a data interchange format based on JSON (JavaScript Object Notation), which has been initially designed for exchanging low frequency radio events and features. It defines several types of JSON objects and how they are combined to represent data related to temporal-spectral features of a time spectrogram (a.k.a., dynamic spectrum), their properties, and their temporal and spectral extents. This implementation is inheriting from the GeoJSON file format. The TFCat python library is implementing this specification and provides a software interface permitting to create, update and validate TFCat objects efficiently.
