At present, the test of the microwave imager electronic assembly cylinder is completed through manual operation, namely the microwave imager electronic assembly cylinder and a radiation source are respectively arranged on respective supports, and the radiation source and a feed source horn of the microwave imager electronic assembly cylinder are aligned through manual movement adjustment, so that the operation is complex, and the test is influenced.
