Abstract
The adaptive beam-former has been widely used in radar, sonar, underwater communications and geophysical exploration, etc. Along with the advances in VLSI technologies, some of the common algorithms for signal processing are now implemented in highly pipelined and regular systolic arrays. Consequently, realtime processing can be realized through parallel processing. In this paper, we have proposed a parallel systolic adaptive beam-former (PSABF), which converges quickly and needs only a very small amount of sampling data to complete the adaptive process. The QR systolic array is adopted as the main algorithm and is combined with the generalized sidelobe canceller (GSC) to solve coherent interference. The results of the computer simulations have shown that the performance of PSABF is very satisfactory.
