- Title
A COMPARATIVE STUDY REGARDING RADIO INTERCEPTION OF FREQUENCY HOPPING SIGNALS.
- Authors
Mitran, Radu; Bechet, Paul
- Abstract
Radio interception deals with detection, classification and monitoring of radio signals. Radio detection using time-frequency analysis is investigated in this paper. Detection capacity for these algorithms is evaluated using simulation and practical measurements. Tactical Frequency Hopping (FH) signals were used for testing the ability of detection algorithms. Energy detector and spectral estimation is tested against FH signals and results are compared with the ones obtained when using time-frequency analysis. The paper demonstrates that, for FH detection, time-frequency works better compared with classic detection (time domain or frequency domain). Gabor Transform is used for time frequency analysis. Parameters of Gaussian window are tuned according to the blanking time of intercepted FH signals.
