| 摘 要： | 针对CFAR检测方法在强海杂波环境中虚警率过高的问题,该文提出了利用二次Gamma核的目标检测方法对SAR图像舰船目标进行检测。该方法可以克服CFAR目标检测方法的缺陷,在强海杂波环境中能有效检测目标,通过实验证明了该方法大大提高了图像的平均信杂比,降低了检测的虚警率。

| Abstract: | Aiming at the higher rate of false alarm for CFAR detection technique in strong clutter environment.A target detection tech-nique based on the quadratic Gamma is introduced.This technique can overcome the limitation of CFAR detection technique and can de-tect the targets in strong clutter environments efficiently.The experiments strongly proved that this technique can heavily improve an image believes the miscellaneous ratio and reduce the false alarm rate. |
