摘　　要：本文针对窄带雷达探测时,目标不在采样波门中心产生距离跨越导致目标检测性能下降的问题,提出一种高效的使用三次样条距离插值的二次迭代检测方法,能够有效减少距离跨越损失。经实测数据统计验证,平均SNR可提升约0.28dB,对于改善目标检测性能有着积极作用。同时该方法简单且计算效率高、对原有雷达系统回波数据存储读写结构、计算架构、处理流程具有继承性,易于工程化应用。The decline of target detection performance results from the situation that the reception of signals is not centered on a sampling strobe when the targets are searching by a narrow-band radar. So an iterative detection method which works efficiently based on cubic spline interpolation is proposed. Then the range straddling loss can be reduced. The measured data shows that SNR(Signal to Noise Ratio) can be improved about 0.28 dB. It imposes a positive effect to improve the performance of target detection. The approach is simple and computationally efficient. Storing and reading method of the radar echo data, computing architectures and processing process of the original radar system can be inherited. So it is convenient for engineering application.
