摘要
跑道异物(FOD)是对影响机场航班起降的外来物质的总称,目前全球绝大多数机场的FOD监测仍然是靠人工完成。为了满足FOD监视手段的迫切需要,本文采用圆弧合成孔径雷达实现机场跑道异物探测;通过比较实孔径扫描和圆弧合成孔径雷达的优缺点,开展信号模型仿真,并与实测数据进行对比验证。结果表明:针对同样目标,圆弧合成孔径雷达的探测距离提高2~3倍,并能有效抑制雨雪等"闪烁"杂波。
Foreign object debris(FOD)generally refers to a certain type of foreign substances,which can influence the taking off and landing of airport flights.Currently,FOD monitoring in the vast majority of airports across the world is operated manually.In order to meet the urgent need for FOD monitoring measures,the imaging technology based on arc synthetic aperture(ArcSAR)is used to detect the airport FOD.The signal model simulation of ArcSAR is conducted by comparing the relative merits between real aperture scanning and ArcSAR,and the simulation data is compared with measured data for verification.The results show that,for the same object,the detection range of ArcSAR can be increased by 2~3 times,and ArcSAR can effectively inhibit"flickering"clutters such as rain and snow.
