Abstract
Beamforming is a significant signal processing technique which can achieve high gain and low sidelobe. It has been widely studied and integrated into various radar systems. In this paper, we mainly focus on the realization of high-speed data sampling, storage and multi-beam forming realizing on FPGA platform. The designed scheme can be integrated with RF circuit to construct a joint test system for evaluating high speed radar systems through Ethernet interfaces. The FPGA based DBF system with low cost can facilitate the design flexibility and reliability, which is also easy to upgrade in practical engineering.
