摘要：

In this work the class of sparse 2D arrays yielding a lower peak sidelobe level when curved in one direction has been characterized. Some arrays contained in this class were subsequently simulated containing 48 x 48 elements. Reductions in the peak sidelobe level of up to 6 dB (from -50 db to -56 db) were recorded., without significant differences in the beamwidth. The arrays used in the simulations have previously been shown to he promising for ultrasonic imaging.
