| 英文摘要 | Aircraft disturbs t he adjacent atmospheric environment in flight, forming spatial distribution features of atmospheric density that differ from the natural background, which may potentially be utilized as tracer characteristics to introduce new technologies for indirectly sensing the presence of aircraft. In this p spheric disturbance density fie scattering light of an atmosp bution of the disturbance de aper, the concept of a long-range aircraft detection based on the atmold is proposed, and the detection mode of tomographic imaging of the heric disturbance flow field is designed. By modeling the spatial distrinsity field, the scattered echo signal images of active light towards the disturbance field at long distance are simulated. On this basis, the characteristics of the disturbance optical signal at the optimal detection resolution are analyzed. The results show that the atmospheric disturbance flow field of the supersonic aircraft presents circular in the light-scattering echo images. The disturbance signal can be further highlighted by differential processing of the adjacent scattering images. As the dis bance signal increases, and the signal intensity and contrast with the background decrease. Under the ground-based observation conditions of the aircraft at a height of 10000 m, a Mach number of 1.6, and a detection distance of 100 km, the contrast between the disturbance signal and the backtance behind the aircraft increases, the diffusion range of the distur |
