A laser communication detection device and method

Abstract

The invention discloses a laser communication detection device and method. A radio frequency signal generation module performs calculation processing on the communication data to be sent to obtain an analog signal; the laser generation module is connected with the radio frequency signal generation module, and the analog signal is used to modulate the laser generation module to obtain Make the laser generation module send out laser signals; the photoelectric detection module obtains the laser signal in the atmospheric channel and converts it into an electrical signal; the signal preprocessing module receives the electrical signal converted by the photoelectric detection module and performs preprocessing; The distance signal and the speed signal are extracted from the electric signal to obtain the distance information and the speed information; the communication signal processing module extracts the communication signal from the preprocessed electric signal to obtain the communication information. By transmitting one signal, it can measure the distance and speed of the target without communication function, and communicate with the terminal with laser communication function. The communication rate is high, which can better meet the actual needs.

Description

technical field [0001] The invention relates to the technical field of laser detection and laser communication, in particular to a laser communication detection device and method. Background technique [0002] Laser communication ranging integration technology is one of the comprehensive applications of laser radar technology, laser communication technology and signal processing technology. It is widely used in many fields such as deep space exploration, intelligent driving, and the Internet of Things, and has broad application prospects in both civilian and military fields. [0003] At present, most lidars meet the radar-related detection requirements of ranging or speed measurement, and laser communication does not have the ranging capability during the entire communication process. The integrated technology of laser ranging and communication generally has the following two methods: the first is the integrated technology of laser ranging and communication applied in deep ...
