| Abstract: | Based on the 3D coordinates of target facet primitives and flying-time of laser pulse, a novel method is presented here to describe the scattering characteristics of Laser Target Detection Device. The scattering power equations of target and aerosol are derived theoretically, as well as the simulating pulses wave of receiving signal is given. According to the amplitude-width information of pulse, a recognition method of discriminating target and disturbing signals is shown. |
| Keywords: | Receiving pulse power Flying-time Amplitude-width method Laser TDD |
