Embodiment Construction

[0052] In the present invention, the upper computer in the darkroom first sends the zero-phase control command to the phased array test box, and the phased array test box sends it to the phased array antenna according to the corresponding control sequence, and the phased array antenna will respond after receiving the control command. Feedback a frame of response frame, when the main control software of the upper computer judges that the phase control of the antenna unit is completed after receiving the response frame of the antenna, the upper computer controls the probe to move to the corresponding spatial position of the unit, and controls the vector network to record the unit corresponding phase. Traverse each element of the phased array antenna in turn, and record the corresponding phase. After the traversal is completed, the main control software uses an algorithm to correct the inconsistency of the phases of each unit. After the correction is completed, repeat the above t...

Abstract

The invention relates to a phased-array antenna automatic test system and a test method. The phased-array antenna automatic test system comprises a vector network, a probe and servo system, a phased-array antenna, a phased-array antenna measurement and control box and an upper computer. Through the upper computer, the vector network, the probe and servo system, the upper computer, the phased-arrayantenna and the measurement and control box in a dark room are integrated to form a closed-loop control system, thereby saving the work of manual control of the probe and servo system and phase of the antenna, realizing seamless combination between a dark room test system and an antenna control system, saving a lot of repetitive work needing to be finished by workers and reducing error rate.

Description

technical field [0001] The invention relates to a phased array antenna automatic testing system and testing method, belonging to the technical field of antenna testing. Background technique [0002] Due to the large inconsistency in the phase of each TR of the phased array antenna, the TR of the antenna needs to be corrected one by one in the darkroom before delivery of the phased array antenna. As the number of TRs of the phased array antenna increases, At the same time, the phased array is developing towards two-dimensional multi-polarization, and the workload of testing phase calibration also increases geometrically. [0003] The traditional test method is to manually go through each unit of the phased array antenna one by one in the darkroom. Manual intervention is required for each unit, usually 600 to 1000 times. The system joint test work is cumbersome, which makes the time required for the production and delivery of the phased array antenna longer and longer, and ta...
