Radar antenna array surface fault detection method and system

Abstract

The invention discloses a radar antenna array surface fault detection method and a radar antenna array surface fault detection system, and relates to the field of radars. The method comprises the steps of building a training set and a test set according to detected data of n modules; randomly selecting the detected data of m modules from the training set to build new training sets, wherein the t new training sets are jointly built; separately training a preset fault judgment model according to the t new training sets, thus acquiring t trained fault judgment models; and separately testing the trained fault judgment model according to the test set, and determining the faulted module according to a test result. According to the method and system provided by the invention, the detected data ofthe multiple modules of the radar antenna array surface is analyzed in a unified manner, the defect of the analysis method that only uses a single fault characteristic quantity is overcome, the faultcan be quickly and conveniently positioned, the radar fault analysis and fault prediction are effectively assisted, the fault detection requirement of the antenna array surface of the active phased array radar can be met, and the wide application value and the market prospect are achieved.

Description

technical field [0001] The invention relates to the field of radar, in particular to a radar antenna array fault detection method and system. Background technique [0002] For the antenna array of active phased array radar, because it combines multiple modules and subsystems, the operating conditions are complex. When a fault occurs, there are many influencing factors. The same fault may have different manifestations, and The same fault phenomenon may also be the result of several faults working together. [0003] At present, in engineering, the fault detection of the antenna array of active phased array radar is more based on a single fault characteristic quantity, and all the fault characteristic quantities have not been comprehensively analyzed, and the diversity and uncertainty of faults have not been considered comprehensively. Due to the complexity of the connection between nature and various faults, the current detection methods cannot meet the fault detection requir...
