Abstract: |
This paper constructs a simulation system of near-field laser imaging for 3D grid model of target, provides some methods for
the key problems, such as the modeling of target and laser transceiver, the calculation of laser echo power, the imaging algorithms
and so on. A target image library is established by a new imaging method in any rendezvous conditions. The four real-time
recognition algorithms which are efficient and suitable for hardware implementation are presented at the conditions of the
image incompleteness, intensive noise and arbitrary attitude of target. The experimental results show that all the four algorithms
can independently recognize the target effectively and a better recognition effect is obtained by the integration of four
algorithms.
