逆合成孔径雷达（ISAR）具有远距离、全天候、全天时工作等优点，目前通过ISAR成像来进行目标识别已得到广泛的应用。ISAR的观测对象是非合作目标，因此ISAR成像具有深远的国防应用背景，受到各国的重视，是竞争激烈、发展迅速的技术领域。-Inverse Synthetic Aperture Radar (ISAR) has a long-range, all-weather, all-time work, etc, currently conducted by ISAR imaging for target identification has been widely used. ISAR target non-cooperative target observation, it has far-reaching defense ISAR imaging application background, attention all, is highly competitive, rapidly developing technology.
