Abstract

The invention discloses large-size object laser radar imaging technology simulation. The technical scheme provided by the invention comprises steps of firstly constructing a total scattering power equation of a laser radar, wherein the equation is that Ps(t) = Pc(t) + Pf(t), Ps(t) represents the total scattering power, Pc(t) represents the coherent scattering power, and Pf(t) represents the non-coherent scattering power; and performing laser one-dimensional range profile simulation on a spherical object or a tapered object. The beneficial effects of the technology simulation are that beneficial technology supplements and effective technology supports are provided for experiment tests or laser radar engineering applications through the large-size object laser radar imaging technology simulation.

Description

technical field

[0001] The invention belongs to the technical field of radar imaging and relates to a large-size target laser radar imaging technology. Background technique

[0002] Laser scattering imaging of large-scale targets is an important imaging technology in the fields of civil industry, national defense and aerospace. Laser imaging includes the intensity image of the target in the detection direction and the distance image projected along the line of sight of the target. Laser scattering three-dimensional coherent imaging technology has important military and civilian application prospects. Laser scattering distance imaging technology uses narrow pulse laser beams to irradiate complex targets to generate target two-dimensional intensity distribution and three-dimensional information of one-dimensional range images. Coherent detection of scattered echoes with different detector distances, obtaining the echo intensity, range image and relative radial distance of co...
