Abstract: |
A principle prototype of 40 Gsample/s high speed photonic sampling instantaneous frequency measurement(IFM) receiver is developed,in which the time-wavelength-interleaved photonic analog-to-digital converter(ADC) technology is adopted.It gets rid of the electronic limitations and breaks through the key technologies of high speed high quality photonic sampling pulses generation,the match of photoelectric interface and the software and hardware realization of high efficient IFM algorithms.It can realize the sampling,quantization and instantaneous frequency measurement of the signals in 20 GHz bandwidth. |
Key words: electronic countermeasure instantaneous frequency measurement 40 Gsample/s high speed photonic sampling match of photoelectric interface |
