| Abstract: |
| Target model was simulated through approximation of target surface elements by plan and quadric surface and one by one connection of piecewise models. Computing velocity was improved using target model simulated by this method. Changkong target drone model was simulated and the target echo signal was computed. It was proved that the simulation results agrees well with the measured by comparing numerical calculation with experimental measurements. It was concluded that the modeling method is feasible for complex targets simulation. |
