Title:
TERAHERTZ SIGNAL GENERATION METHOD AND APPARATUS, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/207442
Kind Code:
A1
Abstract:
Disclosed are a terahertz signal generation method and apparatus, and a computer readable storage medium. The method comprises the following steps: acquiring a hybrid transmission signal corresponding to a radar transmission signal and a communication transmission signal, and acquiring a first optical signal and a second optical signal generated by an optical frequency comb, wherein the first optical signal and the second optical signal are coherent; using a first single sideband modulator to modulate the hybrid transmission signal to a wavelength of the first optical signal so as to obtain a third optical signal; using a combiner connected to the first single sideband modulator to couple the third optical signal and the second optical signal so as to obtain a coupled signal; and using a first optical-electrical converter connected to the combiner to perform optical-electrical frequency mixing on the coupled signal so as to convert the coupled signal to a terahertz signal.
