The Radio Monitoring Complex by Continuous Analysis of Energy Spectra of Radio Signals Based on USRP FPGA and LabVIEW

The purpose of the article is to develop an automated measuring complex for conducting research of radio signals using modern technologies: a software-defined radio device, access to high-speed analog-to-digital signal processing and the use of an FPGA-based platform for the implementation of electronic devices. The relevance of the work is determined by the need to create a universal compact configurable device, that takes advantage of the technologies described above and, as a result, have lower power consumption, weight and dimensions, low cost and stealth. The description of a newly developed hardware and software complex, based on the budget platform of software-defined radio devices, is given. It is operating in the 10 MHz - 6 GHz range, compactly portable, using the hardware capabilities of the FPGA for processing and analyzing the radio signal "on the fly", which implements additional services facilitating analysis for the operator. The use of FPGA allowed to reduce the sweep time significantly.
