摘　　要：为了研究采用紧凑型接收天线的便携式高频地波雷达的目标检测性能并检验组网的可行性,于2013年底在渤海海域进行了雷达组网试验,并将获取的数据与船舶自动识别系统的数据进行了对比.对比结果表明:单站条件下目标漏检的情况经常发生,导致检测概率很低.而通过双站数据融合,可以将检测概率提高10~20个百分点,多数情况下,联合检测概率都超过了50%,最高时更是达到了80%,初步验证了便携式高频地波雷达组网探测目标的可行性.In order to study the target detection performance and the network feasibility of portable high frequency surface wave radar(HFSWR)with compact receiving antenna,radar network experiment was accomplished in Bohai Sea at the end of 2013,and the data recorded were compared with Automatic Identify System(AIS)data.The results show the situation that missing detection occurs frequently,leading to a low probability of detection under the conditions of single station.But by data fusion of dual station,the detection probability can be increased by 10 to 20percent,the joint detection probability exceeds 50%in most cases,and the maximum even reaches 80%,which preliminary validates the feasibility of portable HFSWR network to detect targets.
