The thesis on “Automated portable complex for detecting and analyzing radio signals based on SDR technologies” is devoted to the development of an autonomous device for operation in conditions of limited access to traditional infrastructure. The relevance of the research is driven by the need for mobile and flexible solutions in military operations, rescue missions, and field research.
The main goal of the work was to create an architecture and software and hardware implementation of a compact complex based on software-defined radio (SDR) technologies. As part of the study, a comparative analysis of modern SDR devices was conducted, including HackRF One, Malahit DSP2, Amator SDR, and others, which allowed us to reasonably choose the optimal configuration for building the system.
A block diagram of the device is proposed, which includes a Raspberry Pi CM5 computing module, a BladeRF radio module, a GPS receiver, an SSD drive, a touchscreen display, and a Li-Pol battery. The paper describes the peculiarities of component integration, power supply, heat dissipation, and interface implementation. The system is built on a modular open architecture, which ensures its scalability, adaptability, and ease of updating.
The developed complex is of practical importance as a basis for creating prototypes of autonomous devices capable of radio monitoring and spectral analysis in difficult operating conditions.
