摘　　要：为了提高便携式高频地波雷达(HFSWR)中近距离的风、浪探测能力,提出以单极子-交叉环组合天线为基本单元,构建二元小型直线阵列,进而获得更窄的波束宽度.通过对2015年福建六鳌试验的实测数据处理,将雷达反演所得浪高与浮标浪高数据进行比对,结果表明:在近距离处,组阵后的浪高结果与单个天线所得结果类似;在中距离处,组阵后浪高结果明显优于单个天线.In order to improve the capability of portable high frequency surface wave radar （HFSWR） in offshore wind and wave detection, it was proposed to construct a small linear array with two ele ments, based on the compact cross-loop/monopole antennas, to obtain a narrow beam width. An ex- periment was conducted in LiuAo, Fujian Province during 2015. After comparing the radar wave- height with the wave buoy data, it is found that the nearshore results from the two-element array are almost the same with that from the single antenna, while the offshore results from the two element array are much better than the single antenna.
