摘要:

模拟大场景的雷达照明通常依赖于光传输的几何模型,该模型在很大程度上忽略了突出的波效应。这可以通过相干射线追踪来补救,但这需要孔径的维格纳变换。这种衍射函数在历史上一直难以产生,并且在光学、全息术、同步辐射、量子系统和雷达领域中是相关的。本文通过几何变换和斯托克斯傅里叶变换给出了任意多边形的维格纳变换,并展示了它在蒙特卡罗绘制中的应用。

英文摘要:

Simulating the radar illumination of large scenes generally relies on a geometric model of light transport which largely ignores prominent wave effects. This can be remedied through coherence ray-tracing, but this requires the Wigner transform of the aperture. This diffraction function has been historically difficult to generate, and is relevant in the fields of optics, holography, synchrotron-radiation, quantum systems and radar. In this paper we provide the Wigner transform of arbitrary polygons through geometric transforms and the Stokes Fourier transform; and display its use in Monte-Carlo rendering.
