摘要

麻省理工学院林肯实验室(MIT LL)一直致力于支持多功能相控阵雷达(MPAR)计划,以开发低成本相控阵雷达。麻省理工学院与MACOM共同开发了一种s波段64元双极化相控阵面板,每个元每个极化的辐射功率为6w。第三代面板用于建造76面板全极化AESA雷达,即MPAR先进技术验证器(ATD)。最近在麻省理工学院的射频测试设施中进行了测试,ATD的EIRP为85 dBW,井径指向性为40 dB,波束转向误差小于0.04°。ATD于2018年安装在国家强风暴实验室(NSSL)的国家天气雷达试验台(NWRT)上。本文总结了76面板MPAR ATD的近场试验结果、安装和校准。

Multifunction Phased Array Radar Advanced Technology Demonstrator (MPAR ATD) Nearfield Testing and Fielding
MIT Lincoln Laboratory (MIT LL) has been working in support of the Multifunction Phased Array Radar (MPAR) program to develop low-cost phased array radar. MIT LL along with MACOM has developed an S-band 64-element dual-polarization phased array panel with 6 W radiated power per element per polarization. The third generation of this panel was used to build a 76-panel fully polarimetric AESA radar, the MPAR Advanced Technology Demonstrator (ATD). Recently characterized at MIT LL's RF Test Facility, the ATD has EIRP of 85 dBW, 40 dB boresite directivity, and less than 0.04° beam steering error. The ATD was installed at the National Weather Radar Testbed (NWRT) at the National Severe Storms Laboratory (NSSL) in 2018. This paper summarizes nearfield chamber test results, installation, and calibration of the 76-panel MPAR ATD.
