The 2-D transfer function of the bistatic SAR is obtained. Azimuth position distortion along range existing in the original alogrithm is corrected by mapping from scene coordinate to azimuth-slant distance coordinate. Bistatic SAR date can still be processed by a mono-static SAR processor. The efficaciousness of the proposed algorithm is verified through point target simulations.

The Base Stealer- Robert Francis Poised between going on and back, pulled Both ways taut like a tightrope-walker, Fingertips pointing the opposites, Now bouncing tiptoe like a dropped ball Or a kid skipping rope, come on, come on, Running a scattering of steps sidewise, How he teeters, skitters, tingles, teases, Taunts them, hovers like an ecstatic bird, He's only flirting, crowd him, crowd him, Delicate, delicate, delicate, delicate - now!

摘要］国外某工程，外部网筒由圆柱斜向交叉与环梁编织而成，外网筒柱节点核心面积相比柱截面面积大幅减小，承载力不足，经有限元分析，汇交节点应力状态复杂，阴角区存在明显的应力集中，通过弹性、弹塑性有限元分析，找出了应力集中的原因，进而有针对性地提出了采用钢板凳进行加强的措施，取得了较好的效果。

A detailed model of non-linear parametric excitation vibration coupling the stay cable and the girder, in which the static sag as well as the geometric non-linearity are considered, is proposed in this paper. Based on several numeric examples investigated by the Galerkin method composed with the integration strategy, several kinds of factors effecting stay cable parameter vibration are studied. Another parameter vibration model by the axial excitation is presented and the corresponding nonlinear equations are derived. The smallest excitation amplitude,the transient state and steady state resonance amplitudes, and the changing characteristics of the axial force are obtained by using harmonic balance method. According to numerical examples calculated by numerical integration method, the effects of the inner damping of the stay cables are investigated.
