Compressive sensing (CS) is compared with conventional beamforming using horizontal beamforming of at-sea, towed-array data. They are compared qualitatively using bearing time records and quantitatively using signal-to-interference ratio. Qualitatively, CS exhibits lower levels of background interference than conventional beamforming. Furthermore, bearing time records show increasing, but tolerable, levels of background interference when the number of elements is decreased. For the full array, CS generates signal-to-interference ratio of 12 dB, but conventional beamforming only 8 dB. The superiority of CS over conventional beamforming is much more pronounced with undersampling.
压缩感知（CS）与传统波束形成方法进行了比较，使用了海上拖曳阵数据的水平波束形成。使用方位时间记录进行定性比较，使用信噪比进行定量比较。定性地，CS 表现出比传统波束形成更低水平的背景干扰。此外，当元素数量减少时，背景干扰水平会增加，但仍在可接受范围内。对于整个阵列，CS 产生的信噪比为 12dB，而传统波束形成仅为 8dB。CS 相对于传统波束形成的优势在欠采样时更加明显。
