What is the primary function of software-defined radios (SDRs) in tactical communications?

The primary function of software-defined radios (SDRs) in tactical communications is to provide flexible waveforms and modulation schemes. SDRs are designed to be highly adaptable and can transmit and receive a wide range of frequencies and protocols through software rather than hardware modifications. This flexibility allows military communications to adjust to various operational environments and mission requirements.

By utilizing software, SDRs can easily switch between different communication standards and modulation techniques, enabling rapid changes to the tactical setup as needed without requiring new physical equipment. This adaptability is crucial in dynamic battlefield scenarios where communication needs may change frequently or when interoperability with different forces is necessary.

In contrast, while processing visual data, increasing voice communication range, or storing data are important capabilities in tactical communications, they are not the primary functions of SDRs. SDRs focus on enhancing the communication capability itself through versatile and reprogrammable systems.
