英文摘要：

Broadband beam-forming technology is adopted to process the broadband signal received by array antenna,form the desired beam pattern,enhance the target signal and suppress the interference. Several main methods（including time domain method,frequency decomposition method and frequency invariant method） of broadband beam-forming are reviewed in signal processing. Some typical algorithms in all the methods are compared with simulation results. The influence of beam-forming methods on the array gain of the signal received under different conditions is analyzed.
