摘要：
Under the influence of Doppler frequency-shift, the theory model about targets near-field bistatic scattering is established with PO method and cell-method depending on SCTE. The formula of bistatic RCS is obtained and it can be degenerated to describe monostatic RCS. Then some curves are presented which are in accordance with the results given by references.

摘要：
The electromagnetic (EM) scattering by rivets on the conducting plate is studied for the first time by using electric field integral equation (EFIE) in conjunction with the moment method. The surfaces of the rivets and the plate are partitioned into triangular cells, the current distribution on the patches is represented by sub-domain type basis function, the EFIE is translated into matrix equation by the Galerkin method, then the current coefficient is obtained. The results show the properties of radar cross section (RCS) varying with the incident angle when there are rivets on the plate.

摘要：
The high frequency hybrid technique based on an iterative Physical Optics (PO) and the method of equivalent current (MEC) approach is developed for predicting range resolution of the Radar Cross Section (RCS) in the spatial domain. We introduce the hybrid high frequency method to simulate range resolution of the extremely large target in the near zone. This paper applies this method to simulate the range resolution of the two 1 m×1 m plates and the ship. The study improves the spced of simulating the range resolution of the extremely large target and is prepared for the application of the extrapolation and interpolation in the spatial domain.
