空间可变杂波统计特性和拥挤的海上交通环境，对常用的自适应检测器提出了苛刻的要求。这是因为检测器不能随着杂波统计特性的改变而保持恒定虚警率，当目标进入CFAR部分时也不能调整目标对目标的干扰。为了消除CFAR检测器中存在的上述问题，本文提出了一种独特的带有目标识别电路的双自适应检测器，它是以在常用自适应检测器上附加辅助并行自适应检测器为基础的。 Spatially variable clutter statistics and crowded maritime traffic environment, the commonly used adaptive detectors made demanding. This is because the detector can not maintain a constant false alarm rate as the clutter’s statistical properties change, nor does it allow the target to interfere with the target when it enters the CFAR section. In order to eliminate the above problems existing in the CFAR detector, this paper proposes a unique dual adaptive detector with target identification circuit based on the additional adaptive parallel adaptive detector on the conventional adaptive detector .
