A method is presented to assess the Synthetic Aperture Radar (SAR) resolution of coherent targets. The SAR resolution is usually considered to be a parameter of SAR system and determined by SAR itself. However, the SAR resolution is also relative to the properties of radar targets. In this paper, the relationship between SAR resolution and coherency of radar targets is analysed in detail, and the separable probability is presented as a parameter to assess the SAR resolution.

通常对合成孔径雷达图象分辨力的评定是以雷达系统参数来考虑的。实际上由于合成孔径雷达本身成象的特点,其图象分辨力也是同目标特性密切相关的。本文通过数学分析,将相干目标的分布模型与图象的可分辨条件结合在一起,提出了与目标特性相关的雷达图象分辨力评定标准——可分辨概率,并针对不确定目标的特性提出了平均可分辨概率的概念。针对所提出的分辨力评定标准,本文给出了计算示例,从计算结果中可以看出,目标特性对于雷达图象的分辨力有很大的影响,在设计或者评定雷达图象分辨力时应当考虑到目标特性的影响。

In shipborne radar, the widening first-order sea clutter because of the carrier's movement obscures the ship target and causes the difficulty of detecting target, by spatial super resolution, it is feasible to divide the target and broadened first-order sea echo spectrum. The resolution ability of constrained-MUSIC is not degraded when coherent targets exist and in shipborne HFOTH radar, because the spatial azimuth angle of first-order sea echo can be computed, constrained-MUSIC algorithm can make full use of the known azimuth information to resolute the vessel target, which has the same frequency as the first-order sea clutter but different azimuth angle, so as to realize the spatial high-resolution in HF OTH radar and the three-dimension detection background platform after range-velocity-azimuth resolution is given.

Appropriate transfer of cohesive devices is the guarantee of coherence of the target text in translation from English into Chinese and vice versa. Yet in practice mistranslation often occurs, which results in the incoherence of the translated text or serious errors.
