Stripmap mode SAR raw data generator for ocean scene with large squint angle
A procedure for synthetic aperture radar (SAR) raw data generation for time-variant ocean surface is proposed. The appropriate ocean reflectivity function that takes account of the electromagnetic-ocean wave interaction is transformed on to SAR raw signal based on the distributed surface (DS) model. An efficient and accurate simulation algorithm with time-domain integration along range dimension for squint SAR raw signal is adopted. Moreover, the ocean's dynamics is accounted by means of interpolation based on the dispersion relationship of the time-variant waves. Simulation results are presented to demonstrate the validity and applicability of the proposed techniques.

Solidarity. Reflections on an Emerging Concept in Bioethics. Summary
1. References to solidarity are currently on the increase in public discourse. In the UK and beyond, during economic crises and in a political climate where many feel that mutual assistance has lost currency, calls for a new and forceful emphasis on the meaning of solidarity are increasingly heard. Such appeals to solidarity are inevitably linked to ideas about how societies function, and about how and where the boundary between individual, familial, communal and societal spheres of responsibilities should be drawn.
