一种新型毫米波成象系统已装备在海军研究实验室,并用 NASA/Wallops C—54飞机进行了飞行试验.该系统装有一个摇摆镜和几个可互换的辐射计装置,使得系统特别适应于其工作频率,极化强应和角分辨率的变化.已对该系统做了90GHz 的飞行试验,同时也在22和31GHz 上用一个双频率辐射计进行了飞行试验.本文叙述了成象系统和数据处理,而且介绍了一些在90GHz 进行初次飞行所得的试验结果.
A new type of millimeter-wave imaging system has been installed at the Naval Research Laboratory and conducted flight tests on a NASA / Wallops C-54 aircraft equipped with a rocking mirror and several interchangeable radiometer arrangements that make the system special Adapted to its operating frequency, polarization, and angular resolution changes have been made to the system 90GHz flight test, but also in the 22 and 31GHz with a dual-frequency radiometer for flight test.This article describes the Like system and data processing, and introduced some of the experimental results from the initial flight at 90 GHz.
