Two factors in targets near-field RCS calculation

摘要

Considering antenna pattern and Doppler frequency-shift separately, the theory model about targets near-field scattering is established from a simple target, using PO (physical optics) method depending on SCTE(Scattering from Complex Targets and Environments)system.Then some curves are presented which are in accordance with the results given by references. The calculated results show that the influence of the factors over targets near-field RCS are complex and important. This work has practical engineering value in the modern and high science and technology warfare.
