| 摘要: |
| 针对当前空中非合作目标中旋转部件位置估计方法稳健性不足的问题，在分析旋转部件在高分辨距离像和逆合成孔径雷达像中分布特性的基础上，提出应用逆合成孔径雷达像的方位向距离单元熵和局部径向距离单元熵的旋转部件位置估计方法。该方法能够提升空中非合作目标逆合成孔径雷达成像过程中旋转部件信号分离的准确度。仿真数据和实测数据处理结果证明了所提方法的有效性，通过在实测数据中叠加额外噪声，进一步检验了所提方法对噪声的稳健性。 |

| Abstract: |
| Aiming at the lack of robustness for current position estimation method to rotation parts in aerial non-cooperative targets, a position estimation method using cross range cell entropy and local range cell entropy was put forward, which was based on analyzing of distributing characteristic of rotation part in high resolution range profile and inverse synthetic aperture radar. The proposed method promoted the accuracy of signal separation for rotation part when inverse synthetic aperture radar imaging was applied to aerial non-cooperative targets. The real data simulation results showed validation of the estimation method, and the steadiness of the estimation method was further tested by applying real data with additional noise. |
