Abstract

Concerning future ultra wideband (UWB) real-time measurement of electromagnetic spectrum demand in electromagnetic battlefield, this paper proposes a frequency-time mapping measurement method based on microwave photonics. Frequency-time mapping, or real-time Fourier transform, maps the input ultra-wideband electromagnetic spectrum information to the output time-domain waveform. The electromagnetic spectrum signal is modulated to light by CS-SSB modulation, and frequency-time mapping is formed by using electrically modulated micro-ring. Through simulation verification, the method can achieve frequency measurement of panoramic bandwidth signal from100MHz to 30GHz.The frequency resolution can reach 80 MHZ, whose scanning time is less than 20us. The method can achieve ultra-high speed, high-precision, broadband measurement of wideband complex electromagnetic spectrum situation, providing technical support for future electromagnetic spectrum operations.
