Considering the deficiency of the present FS algorithm in the case of high squint angle,this paper proposes an equivalent side-looking method for squint FMCW SAR.

In order to solve the difficult problem that the conventional seismic processing system cannot process the seismic data on high sample rates and on the SH wave with lower velocities, this paper proposes processing the shallow layer seismic data resolution with an equal effect processing method and improving data resolution under the circumstances of assuring high signal noise ratio.

Say a few words about our understanding and suggestion on the Design by Analysis,including the modeling of finite elements, the stress classification of results by finite element method and the equivalent linearization method etc.

Say a few words about some understanding on the design by analysis and design by plasticity, the self-limiting property of peak stress, and the equivalent linearization of stresses computed by the finite element method etc.
