摘　　要：常规扫描相关积累(SIC)算法在探测快速运动目标时易失效,提出了一种与海杂波抑制技术相结合的新型SIC算法.新算法由两分支组成:一个分支通过扫描加权对杂波进行衰减;另一分支确保快速目标的探测.应用海杂波抑制技术可以进一步提高信杂比,降低雷达检测门限,增大小目标的检测概率.仿真结果表明,本方法显著提高了舰载雷达探测小型快速运动目标的能力.Conventional scan-to-scan integration correlation (SIC) algorithms are ineffective in detecting small, fast targets. This paper presented a new SIC algorithm, together with clutter suppression measures that remove or decrease sea clutter. The algorithm divides the scan-to-scan integration (SI) into two branches: one provides optimum clutter attenuation by means of SI weighting while the other ensures that targets are detected even if they are fast. Sea clutter suppression can reduces detection thresholds, at the same time, increase signal-to-clutter ratio. The simulation results show that the proposed approach greatly improves the detection capability for warship radar.
