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