在已往的十年中,国外已有不少研究单位用逆合成孔径雷达(ISAR)对飞航中的飞机进行了二维成象。虽则雷达的纵向 (距离向) 分辨力和横向 (方位向) 分辨力均设计得相当高,但实际得到的分辨力和清晰度却不理想。本文旨在指出其原因,并以国际上八十年代对飞机成象的实例为证。
In the past ten years, many overseas research institutes have used the inverse synthetic aperture radar (ISAR) to conduct a two-dimensional imaging of the aircraft in flight. Although the resolution of the longitudinal (range) and horizontal (azimuth) resolutions of the radar are designed to be quite high, the resolution and sharpness actually obtained are not ideal. The purpose of this paper is to point out the causes and to prove the examples of aircraft imaging in the 1980s.
