Research on High-speed Detection Method of Radar Signal Based on RFSoC

This paper proposes a real-time radar signal detection method based on RFSoC and parallel Fast Fourier Transform (FFT) architecture, suitable for electronic warfare (EW) applications in electronic reconnaissance aircraft. The proposed method utilizes high-speed Analog-to-Digital Converters (ADC) and high-performance heterogeneous processing units integrated in RFSoC, combined with parallel FFT algorithm, to optimize the radar signal detection architecture. It improves the time-accuracy trade-off in large point FFT processing, enabling the electronic reconnaissance aircraft to detect radar signals containing any number of carriers with instantaneous bandwidth of 2 GHz and frequency resolution of 1 MHz in 3 us. Both Matlab simulation and real-world experimental results are presented to validate the rationality and reliability of the design, providing a reference for the design of modern high-performance electronic reconnaissance aircraft.
