Hatasdr

Hatasdr is an open-source software framework and toolkit designed for software-defined radio (SDR). It aims to facilitate the development, testing, and deployment of digital radio algorithms by providing a modular, extensible environment where signal processing blocks can be assembled into custom workflows. The project is used by hobbyists, educators, and researchers to prototype new waveforms and processing techniques without needing specialized hardware for every experiment.

The core of hatasdr features a modular dataflow architecture that supports a range of digital signal processing tasks, including sampling, filtering, modulation and demodulation, waveform generation, and spectral analysis. It offers interfaces in multiple programming languages, typically including Python and C++, to enable rapid development and integration with existing tools. Real-time processing capabilities and debugging support are common goals in the framework, along with simulation or offline processing modes for algorithm testing.

Hardware support is designed to be flexible, with a focus on compatibility with various SDR front-ends and RF transceivers. HatASDR provides adapters or drivers to connect with popular devices and to abstract hardware specifics, allowing users to experiment with different hardware configurations. This hardware abstraction supports both actual radio experiments and educational environments where hardware may be limited.

The project is maintained through community contributions and releases under an open-source license. Documentation, tutorials, example projects, and API references are typically provided to assist new users in getting started and to help experienced developers extend the framework. HatASDR is commonly discussed alongside other SDR platforms as a complementary option that emphasizes modular DSP workflows and rapid prototyping.
