The equivalent depth definition method of stereo air gun array
摘要
Abstract
There is no evidence based on defining the equivalent depth of stereo air gun array. In order to have a comparison with the conventional air gun array, an optimal method for determining the equivalent depth of stereo air gun array is required. Based on the technology of air gun simulation under practical conditions. This paper gives some representative simulations of stereo air gun array and proposed two equivalent depth definition methods: geometric weighting equivalent depth method(GWEDM) and notch frequency equivalent depth method(NFEDM). In addition, the influence factors affecting the NFEDM is found, such as: the depth of air gun sub-array and the direction of hydrophone. By a detailed analysis of actual data, a effective equivalent depth definition method in practical production is present.关键词
