| Abstract: |
| The problem of direct-path-interference in the bistatic digital phased array r
adar is analysed.According to the radar work mode,sig
nal processing architecture and radar practical application,several technologies
are studied including transmitter-receiver isolat
ion,digital beam adaptive nulling,frequency agility,adaptive canceling and pulse
compression to solve above problem. The theoretical ana
lysis and computer simulation indicate that the presented technologies can solve
the problem of direct-path-interference in the bistatic digital array radar. |
