摘要: |
在强杂波背景下设计有效的海上雷达目标检测器是相当困难的。本文提出了一种基于海面散射的分维持性的雷达目标检测方法。它利用海上目标雷达回波与海杂波在分维持性上的差异来对海上舰船目标进行检测。将该方法用于实地录取的舰船雷达弱目标的回波,取得了较好的检测效果。 |

Abstract: |
It is very difficult to design an effective detector to spot ship targets. In this paper,a new method of detection based on fractal characteristics of sea-surface scattering is proposed. By comparing the difference in the fractal dimension between the sea c1utter and the echoes from a target,an effective detection of the radar ship targets can be realized. In order to test this method,we use the real radar returns of ship targets for detection and a better result has been achieved. |
