REDHAWK is a software-defined radio (SDR) framework designed to support the development, deployment, and management of real-time software radio applications. To support the design and development of software applications, REDHAWK provides tools that allow development and testing of software modules called "Components" and composition of Components into "Waveform Applications" that can be seamlessly deployed on a single computer or multiple network-enabled computers.

The REDHAWK integrated development environment (IDE) provides tools to support development of REDHAWK software. The development and deployment of REDHAWK Applications are aided by graphical editors and drag-and-drop Waveform construction. The IDE allows users to interact with and control multiple running REDHAWK instances and applications.

Final Release of REDHAWK 2.0 (December 10, 2015) - The effort in REDHAWK 2.0 focused on improving system management, establishing a core set of REDHAWK assets, and enhancing the IDE user experience. This effort included:

Within the Core Framework, system scalability was addressed by creating or expanding system managers (connections, allocations, and events), improving the dependency management structure for Components, and by further automating the process of distributing processing tasks. Processing performance improvements focused on NUMA balancing related to both processing and data ingest/egress. Finally, the burden on the component developer was reduced by making it easier to access system resources, simplifying properties, shifting BulkIO data management from packet-based to stream-based, and simplifying the structure of generated code.

In the IDE, diagrams were re-implemented to provide a refreshed look and a simplified, more slimlined display of diagram elements. New visualizations were added to help developers more quickly and easily create Waveforms and Nodes and monitor and debug them more easily at runtime. Shared library support was improved to enable developers to better share code between Components and Devices, while creating software that follows REDHAWK standards for easy reuse and deployment in REDHAWK systems. Namespaces were added to assist with upgrades, allowing multiple versions of a Component to be installed on the same system. Additionally, namespaces enable developers to more clearly differentiate development efforts like forked projects or contributions by different organizations.

For the REDHAWK assets, consistency was achieved by using common Port types for similar types of data and renaming Ports to establish a consistent naming convention. The set of assets was expanded to include two new assets for file I/O, a Component for decoding FM RBDS, a Component for PSK demodulation, an FEI Device simulator for generating FM RDS streams from audio files, and a set of Waveforms that collectively demonstrate the use of each Component. The set of assets was focused by removing deprecated Components (whitenoise, DataReader, DataWriter, freqfilter, medianfilter, unwrap, and BurstDeserializer). Core assets were used as examples of how to exercise new REDHAWK features. For example, domain awareness was leveraged by FileReader and FileWriter, the new BulkIO stream API was utilized by psd, sequences within struct properties were added to sinksocket, the updated shared library support was used to re-implement each shared library, and each asset was moved into the "rh" namespace.

Getting Started

For detailed installation instructions, refer to the Installation Instructions. For a quick introduction to REDHAWK, refer to the Getting Started Guide.


REDHAWK consists of the Core Framework, development tools, libraries, and reusable building blocks. The Eclipse-based REDHAWK IDE can be used to aid in the development and deployment of REDHAWK Applications. Additional REDHAWK Eclipse-based products are built from a subset of the IDE plug-ins including the SCA Explorer.
