摘要
文章对番禺和花都两部AXPT0364型X波段双偏振相控阵天气雷达开展波束宽度、波束精度、最大副瓣电平、交叉极化隔离度、双线偏振波束角度误差和3dB波束宽度误差等主要天线技术指标测试,运行前后的测试结果证明两部相控阵天气雷达运行3年后天线整体技术指标仍满足X波段双线偏振一维相控阵天气雷达测试大纲和原出厂要求,但最大副瓣电平和交叉极化隔离度有下降趋势,在今后的业务运行中需要重点关注。
The article conducted tests on the main antenna technical indicators of the AXPT0364 X-band dual polarization phased array weather radar in Panyu and Huadu,including beam width,beam accuracy,maximum side lobe level,cross polarization isolation,dual polarization beam angle error,and 3dB beam width error.The test results before and after operation showed that the overall technical indicators of the two phased array weather radars still met the the X-band dual polarization one-dimensional phased array weather radar testing outline and original factory requirements after 3 years of operation.However,the maximum side-lobe level and cross polarization isolation showed a downward trend,which needs to be given special attention in future business operations.
