Detection technology of remnant material in space equipment based on multisensor data fusion

The internal structure of Aerospace electronics device is complex, and there are many unknown factors in the process of thetransmission of remnant material signal, leading to serious interference of data. In order to solve the problems of weak interferenceresistance in the process of the transmission of remnant material signal, easy to overlap interference signal and unable to identifyaccurately, the remnant detection method of aerospace electronic device based on multi-sensor data fusion is used. The same signal isused to extract by multi-sensor, then determine the weight of correlation function through correlation processing of pulse, and obtain thesupport matrix and weight moment array, then output the result of pulse group after data fusion. According to the result of theexperiment, the multi-sensor data fusion method can effectively restrain the signal interference and significantly improve the detectionaccuracy of remnant objects.
