| Abstract: |
| With the fast development of information technology and the increase of spectrum
user,spectrum has become a very rare resource. Due to large amount,multiple fu
nctions,wide operation band and complex electromagnetic environment of avionics
equipment,co-site interference is inevitable. It is a key
point for a good plan of frequency in the flight-test. Based on the analysis o
f the avionic communication system, a frequency management method is introduced w
hich uses the spectrum sensing technology. This method can improve the spectrum usa
ge and support the analysis and rebuilding of the flight-test data, and improve
the evaluation veracity of the avionic communication system′s flight-test. |
