Abstract

The invention discloses a terahertz signal generation method and device, and a computer readable storage medium, and the method comprises the steps: obtaining a mixed transmitting signal correspondingto a radar transmitting signal and a communication transmitting signal, and obtaining a first optical signal and a second optical signal which are generated by an optical frequency comb and have coherence; modulating the mixed transmitting signal into the optical wavelength of the first optical signal through a first single side band modulator to obtain a third optical signal; coupling the thirdoptical signal with the second optical signal through a combiner connected with the first single side band modulator to obtain a coupling signal; and performing photoelectric frequency mixing on the coupling signal through a first photoelectric converter connected with the combiner so as to convert the coupling signal into a terahertz signal. According to the invention, the long transmission distance performance of terahertz signals is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and computer-readable storage medium for generating a terahertz signal. Background technique [0002] The invention of radio ushered in a new era in human history. Of the various radio applications hitherto known, two of the most prevalent and prominent are wireless communications and radar detection. wireless communication systems and radar sensing systems are designed and developed in completely different ways, and although both use radio frequency transceiver functional blocks, there is little difference between them except for some application examples of system fusion, such as secondary surveillance radar systems or identification friend or foe systems, etc., are generally independently researched and developed in most cases. [0003] Radar-communication fusion (integration of wireless communication system and radar sensing system) t...
