摘要
针对步进频率雷达中存在的距离像模糊以及循环移位现象,分析了距离像循环移位的原因。在此基 础上提出了一种采样相位补偿解距离像模糊的新算法。该算法具有物理意义明确、补偿精度高、适合于在DSP中 实现流水处理等优点。采用仿真和实测数据对其进行了验证。
In this paper, the multi-value phenomenon in high-resolution range profiles of stepped frequency radar is analyzed. Based on it, a new algorithm to achieve unambiguous range profiles is proposed, which is an essential pre-processing in target extraction. This algorithm has the advantages of high compensation precision and high processing efficiency. The algorithm has been verified with both simulation and experimental data.
