The problem of direct-path-interference in the bistatic digital phased array radar is analysed.According to the radar work mode,signal processing architecture and radar practical application,several technologies are stud-ied including transmitter-receiver isolation,digital beam adaptive nulling,frequency agility,adaptive canceling and pulse compression to solve above problem. The theoretical analysis and computer simulation indicate that the pre-sented technologies can solve the problem of direct-path-interference in the bistatic digital array radar.
