Abstract
Adaptive digital beamformer (ADBF) is effective in suppressing unexpected interferences arriving at the antenna array. An ADBF intellectual property (IP) using the floating point data type has been developed with high-level synthesis (HLS) technology. This IP computes the real-time adaptive weights of each sub-array to spatially filter the arriving signals. The design has been validated in a recent airborne flight test and the result demonstrated the effectiveness of this approach.
