| 摘 要： | 针对雷达高分辨距离像（HRRP）目标识别问题，对目标回波进行子带划分，分别进行幂变换预处理获得子带距离像，通过实验证明HRRP不同频段的子带距离像均含有目标信息，可以从中提取特征信息用于目标识别。提出一种相关系数相加法子带融合识别算法，由于该方法充分利用了回波信息，因而能获得更好的识别性能，实验仿真验证了这一结论，分析表明算法具有计算复杂度低的优点，因此可实际应用于雷达自动目标识别。 |

| Abstract: | For solving some problems on target recognition based on HRRP （high-resolution range profile）, the complex returned echoes from the target scattering centers were firstly divided into some sub-bands. Then the power transformations were acted on every sub-band and its HRRP was derived respectively. Experiments illustrated that each sub-band HRRP contain target information which could be adopted to realize target recognition. A new target recognition algorithm based on confused sub-band HRRP, named sum of correlated parameters method, was proposed. Thanks to the full utilization of information contained in echoes, the algorithm improved the recognition performance. The experiment results based on measured data showed this conclusion. Analysis also indicated the low computation complexity of the algorithm. The algorithm could thus be used to radar automatic target recognition （RATR）. |
