Radar antenna array fault detection method and system

Abstract

The invention discloses a radar antenna array fault detection method and system, and relates to the radar field. The method includes: constructing a training set and a test set according to the detection data of n modules; constructing a new training set from the detection data of m modules selected from the training set, and constructing t new training sets; respectively according to the t new training sets Train the preset fault discrimination model to obtain t trained fault discrimination models; respectively test the t trained fault discrimination models according to the test set, and determine the faulty module according to the test results. The invention can perform unified analysis on the multi-module detection data of the radar antenna front, overcomes the deficiency of only relying on a single fault characteristic quantity analysis method, can quickly and conveniently locate the fault, effectively assists the radar fault analysis and fault prediction, and can meet the active The fault detection requirements of the antenna array of phased array radar have broad application value and market prospect.

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...
