Abstract:

A microwave photonics deceptive RF regeneration method with multi-characteristic regulatory is proposed for radar jamming. In this scheme, Doppler frequency shift (DFS) is implemented by a Serrodyne structure based on the modulation of a sawtooth wave signal. This structure can effectively fulfill a small frequency shift of the original carrier through carrier-suppressed single sideband modulation without any filter, which makes a small frequency shift possible for a wideband radio frequency signal. The phase shifting of the RF signal is achieved by adjusting the bias voltage of the modulator. The RF modulation pulse signal is stored in an optical loop. Two semiconductor optical amplifiers and an Erbium-doped optical fiber amplifier are combined to control the delay time and ensure the fidelity. The experimental results show that the DFS from 100 Hz to 5 MHz can be realized and its minimum frequency step is 50 Hz. The phase shift covers from -180° to 180°. Furthermore, the RF signal can be delayed more than 100 μs with a small signal-to-noise degradation (<7.32 dB). This method supplies flexibility of multi-parameter adjustment, and has broad potential applications in modern radar interference. IEEE
