Sparse Cylindrical Sonar Arrays

IEEE Journal of Oceanic Engineering, 2008
Sparse arrays offer a means for reducing the cost and complexity of beamforming systems. Most of the work in the literature has focused on sparse linear arrays with isotropic transducer elements, which simplifies analysis greatly. In this paper, we will focus on multibeam cylindrical arrays using highly directive elements for use in fishery ...

APPLICATION OF ARRAY PROCESSOR TO SPARSE ELIMINATION

Proceedings of SPE Reservoir Simulation Symposium, 1979
Abstract The Floating Point Systems array processor AP120B can be used to efficiently solve large systems of linear equations by a sparse Gaussian elimination technique. Bench mark tests show the following results: For LU factorization, the AP120B requires 22 to 35% less CPU time than the IBM 370/168; for forward or

Accessing Sparse Arrays in Parallel Memories

1983
The concept of dense and sparse execution of arrays is introduced. Arrays, themselves, can be stored in a dense or sparse manner in a parallel memory with m memory modules. Hardware is proposed for speeding up the execution of array operations of the form C(c//0 plus cI) implied by A(a//0 plus al) OP B(b//0 plus bI), where a//0, a, b//0, b, c//0, c are
