A Novel Power Combination Method by Time Reversal Pulse Compression Technique

The electromagnetic time-reversal (TR) technique has the characteristics of spatiotemporal focusing in a cavity (TRC), which can be used for pulse compression, thus forming an with high peak power. A time-reversed pulse-compression method single channel compression gain. However, only generate limited This paper proposes novel TR power-combination multichannel TRC to obtain higher power based on theory. First, model is given, and crosstalk properties associated influence reversal performance are studied. Then, performances such as combined signal noise ratio (SNR) gain, analyzed by numerical simulation experimental methods. results show that proposed obvious advantages over methods using cavity, more convenient combination.
