Design of a Multi-Mode RF Signal Acquisition and Storage System Based on FPGA

Le résumé fourni par la source

With the development of modern electronic technology, the demand for large-capacity, high-speed and real-time signal acquisition is becoming more and more urgent. In this paper, a multi-mode RF signal acquisition and storage system based on FPGA is designed to meet such demand, and realize high-speed acquisition, processing, transmission and storage of RF signals in the frequency range of$1 \sim 18 \text{GHz}$and the maximum instantaneous bandwidth of 2 GHz. The system, designed for radar, electronic reconnaissance, and other application scenarios, features six innovative acquisition modes, four bandwidth configurations, and two storage formats, offering ease of use, flexibility, and broad applicability. The trigger acquisition mode, which synthesizes various conditions of time, frequency and parameter domain, can accurately capture the target signal under strong interference conditions and achieve efficient acquisition.
