Abstract

本发明公开了一种全光太赫兹包络检波方法，涉及光载太赫兹技术、包络检波技术领域，通过超宽带电光处理技术，将接收的太赫兹导频和目标电信号转换成单边带光信号；上路径采用激光注入锁定技术来滤除目标光信号并放大导频光功率，下路径通过光滤波技术来保留目标光信号；对上下路径的光信号进行耦合，再通过宽带电光拍频技术将光信号转换为中频电信号，然后进行数字采样来恢复目标通信或感知信息。本发明还公开了一种全光太赫兹包络检波接收系统，本方法能有效提升太赫兹信号包络接收带宽，解决电子包络检波器的带宽受限问题并提升检波灵敏度；此外，利用导频与目标信号的同源特性，可以消除目标信号频偏干扰，降低系统复杂度。
