Automatic test system for high-isolation active antenna array surface

Abstract

The invention relates to an automatic test system for a high-isolation active antenna array surface, which comprises automatic test system software, a signal conversion center and test equipment. The automatic test system software performs self-closed-loop adjustment on the signal power of each channel, automatically writes and reads back a configuration item file, compares a read-back result with a standard result, and analyzes a test result of an antenna. The signal conversion center builds a radio frequency signal transmission link for the antenna and the test equipment, automatically completes switching of an electronic switch according to the software requirement of the automatic test system, builds a required radio frequency path, and adjusts the size of signal power at the same time. The test equipment provides various signals required by the test and sends the test result back to the automatic test system software. According to the invention, manual operation links are greatly reduced, the test efficiency is improved, and the debugging period is shortened. By means of the system, normalized and standardized debugging can be achieved, the debugging efficiency is improved, and meanwhile all performance indexes of the antenna are guaranteed.

Description

technical field [0001] The invention relates to the field of radar, in particular to an automatic test system for a highly isolated active antenna array. Background technique [0002] At present, with the rapid development of science and technology, radar has been gradually upgraded from the passive mechanical scanning radar of the last century to the current active phased array radar. The active phased array antenna, the performance of the antenna also has a more significant impact on the radar machine. However, there are many debugging procedures for active phased array antennas. Among them, the near-field trimming and pattern testing stages are the key stages that affect the antenna indicators. The procedures at this stage are complicated. At present, semi-automatic debugging is the main method, and it is dependent on debugging personnel. High, so there are problems such as unstandardized test parameters, low efficiency of manual switching of test ports, poor amplitude a...

However, there are many debugging procedures for active phased array antennas. Among them, the near-field trimming and pattern testing stages are the key stages that affect the antenna indicators. The procedures at this stage are complicated. At present, semi-automatic debugging is the main method, which is dependent on debugging personnel. High, so there are problems such as unstandardized test parameters, low efficiency of manual switching of test ports, poor amplitude and phase stability of test signals, programming errors in configuration item files, and inability to analyze test data in a timely and effective manner. These problems limit The improvement of antenna production and debugging efficiency makes the production delivery cycle of the radar machine not effectively guaranteed
