Design of Simulations for Multipath Effect of the Approaching Landing System and Implementation

Based on the instruction of the multipath effect of the approaching landing system, the construction of the scatter model database for the complex environment on the airports was completely demonstrated. According to the principle of electromagnetic scattering arithmetic, different scatters select different model. On the other hand, the aircraft diffraction and reflection was simulated correctly. The result indicates that the calculation coincides with the measured result.The feasibility of the proposal in system simulations is proved.
