Abstract
We present a photonic compressive receiver, where the frequency information of the captured signal is directly mapped to the time intervals between compressed pulses for multiple microwave frequency measurement. The theoretical measurement error, multiple-frequency resolution and effective measurement range are derived. The effects of dispersion deviation and the electrical bandwidth are also discussed. The theoretical results are verified by the measured pulse waveforms and frequency-time mapping relationship. A photonic compressive receiver with an effective measurement range of 42 GHz, a multiple-frequency resolution of 1.2 GHz, a measurement accuracy of 88 MHz and a signal interception period of 27 ns is experimentally obtained.
