Abstract :
The adaptive beamforming problem is solved using an algorithm-architecture-arithmetic combination that can be used for a small platform such as are found on aircraft or sonobuoys. The arithmetic used is the RNS system implemented on an array of processors that can be reassigned as the algorithm proceeds. The underlying algorithm is a modified Gaussian elimination. The (non-RNS) division operations are eliminated in favor of some scaling and the adaptive use of the processor array to accommodate the growth in dynamic range
