摘要

考虑了合成孔径雷达(SAR)的聚焦问题，特别注意在合成孔径的近场聚焦区域超过十年或更长的带宽，以保持目标共振特性的方式。给出了一个减少计算负荷的近似值。对该近似值的误差分析定量地说明了保证聚焦深度足以保持长时间目标共振效应所需的条件

Focusing of synthetic aperture ultra wideband data

The synthetic aperture radar (SAR) focusing problem is considered, with special attention given to focusing an area in the near-field of the synthetic aperture over a decade or more of bandwidth in a manner that preserves target resonance characteristics. An approximation that reduces the computational load is shown. An error analysis of the approximation shows quantitatively what conditions are required to guarantee that the depth of focus is adequate to preserve long-duration target resonance effects.<>
