| Popis: | Multipath interference is the main factor which has influence in super-low-altitude detection. Aiming at solving the problem of detection for super-low-altitude target, anti-multipath methods under concrete environment are studied here. First, antenna radiation pattern of seeker is introduced to modify traditional four-path method. Then, the hybrid method combining physical optics (PO) and method of equivalent currents (MEC) is used to calculate the scattering electric field of target. Compared to the method of moment (MoM), the PO + MEC hybrid methods are of high accuracy. Finally, the multipath interference scattering from interaction between the target and the environment under the condition is studied and analysed in detain. The simulation results are useful in military application. |
