| Abstract: |
| The compositon and signal format of 1090ES ADS
-B system are introduced,a scheme for single conversion superheterodyne interm
ediate frequency(IF) digital 1090ES ADS-B equipment is proposed,including antenn
a design, T/R module design, terminal module design and built in test equipment(
BITE) design. The key technical parameters are calculated, and the primary techn
ical features are described
. The scheme has been successfully applied in engineering, and the result is sat
isfyi
