Solid-state radar device based on indium gallium arsenide detection

Abstract

The invention relates to a solid-state radar device based on gallium indium arsenide detection. The solid-state radar device mainly comprises a substrate, a transmitting unit, a receiving unit and a control unit. Wherein a short-wave infrared light source array in the transmitting unit can generate laser of a short-wave infrared band, and the structure details of a target object in an external space can be obtained after short-wave infrared laser echoes are processed and analyzed by utilizing the characteristics of high frequency, wide bandwidth, narrow beam and the like of the short-wave infrared laser; therefore, the active detection capability and the object recognition performance of the short-wave infrared solid-state radar are enhanced. Besides, a reflector group in the transmitting unit reflects and gathers the straightened short-wave infrared laser, so that the components are compactly arranged to achieve the purpose of reducing the size of the device, the energy intensity and polarization angle of the gathered laser can be improved, and the detection capability of the short-wave infrared laser to an external space is enhanced.

Description

technical field [0001] The present application relates to the technical field of laser radar, in particular to a solid-state radar device based on gallium indium arsenide detection. Background technique [0002] With the development of sensor technology, artificial intelligence, pattern recognition and intelligent control, industrial automation has been accepted and applied by a large number of manufacturing enterprises. Advanced manufacturing has become the future development trend of the manufacturing industry. As the front end of information collection and transmission, various Type sensor is an indispensable core device in the intelligent system. Among them, laser radar is a sensor that detects the position, speed, angular position and other characteristic quantities of the target object by emitting laser beams. Its working principle is to emit laser beams to the target object and then receive the laser echo reflected from the target object. After comparing and processi...

Problems solved by technology

[0003] At present, conventional lidar has some shortcomings. It is greatly affected by the weather. Rain, snow, and fog will cause the detection range to drop significantly. In addition, smoke and dust will also affect the detection range of this type of radar.

Although some technicians also try to use short-wave infrared lasers to enhance the detection performance of conventional laser radars, due to the particularity of short-wave infrared lasers, there are high requirements for the structure and signal processing of radar equipment, so the existing short-wave Infrared laser radar technology is not yet mature enough, there are many deficiencies in product structure and performance, which seriously affect product reliability, and cannot be popularized and applied in a wide range of fields
