Özet

Adaptive beamformers are widely used in radar, sonar and communications applications. They increase the directivity of the sensor system to the target while supressing the interfering signals. The beamforming is accomplished by adjusting the weights of the sensors. Optimal weight extraction based on systolic structures have been the subject of various researches. Systolic algorithms are parallel and fully pipelined structures which improve the performance of the beamformer. This paper presents the analysis of the Minimum Variance Distortionless Response (MVDR) beamforming system based on a folded systolic structure. The folded structure of the systolic array reduces the die size of the hardware implementation while the systolic architecture improves the throughput ratio of the beamformer.
