摘要：

This paper describes the design and in-house development of FPGA based Digital Beam Forming Hardware for 16 elements configuration. Key function of the System involves electronic steering of beam in desired direction to provide antijamming feature in communication and navigation satellites. This system has capability to maximize the received power in the direction of signal of interest & minimize the power in the direction of interference. Digital down conversion (DDC) technique is incorporated in the design for providing flexible channel architectures. Dynamic phase calibration and weight uploading facility is included to provide beam forming capability in real time without any hardware penalty.
