| Summary: | This study uses adaptive digital beamforming to provide high isolation between a transmitter and a receiver, which proved effective in achieving simultaneous transmit and receive. Uniform linear array is chosen as the research object, and the cost function is constructed by combining the coupling matrix and beam pointing constraints; then the optimal weighted vector is obtained under the linearly constrained minimum variance rule. The method will provide at least 110 dB isolation without affecting the performance of target detection, which provides certain reference significance in engineering. |
