Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor lidar, and in particular, to a method and system for remote detection of an aircraft based on a semiconductor lidar. Background Art

[0002] In the field of remote detection of aircraft, traditional technical means are difficult to meet the current complex flight environment and high-precision detection requirements. Conventional radar systems operate based on specific electromagnetic frequency bands. When detecting at long distances, limited by the wavelength and signal processing methods, the detection sensitivity for small-sized and low-reflectivity targets is poor. With the progress of semiconductor technology, semiconductor lidars have been gradually applied to remote detection of aircraft. However, when detecting at long distances, the laser signal is significantly attenuated due to the absorption and scattering of substances such as molecules and aerosols in the atmosphere, resulting in a significant reduction in the detection distance and accuracy. Moreover, limited by the optical field of view angle of a single semiconductor lidar, it is difficult to achieve a dead-angle-free coverage of a large airspace around the aircraft, there are detection blind spots, and it is difficult to meet the growing demand for precise perception of the environment around the aircraft in terms of detection accuracy and resolution, making the overall detection performance far from reaching the expected level.
