Description

technical field [0001] The invention belongs to the field of pulse radio, in particular to a system for generating and transmitting pulse radio signals and a control method thereof. Background technique [0002] Pulse radio technology has a series of unique advantages such as simple system structure, low cost, and low power consumption. It has many applications in the fields of radar detection, short-range wireless communication, wireless sensing, and radio frequency identification. The application scenarios of pulsed radio technology are sensitive to cost, power consumption and volume, so low power consumption, low complexity and miniaturization of the system have always been research hotspots in industry and academia. [0003] At present, there are two main types of pulse signal generation methods: photoelectric methods and electronic methods. The photoelectric method can obtain pulses with picosecond (ps)-level width and good consistency, but the conversion efficiency is...
