线元细分观测系统是在常规二维观测系统三维面元理论基础上发展的一种全新的二维观测系统。通过合理地布设炮检点位置, 达到线元可分的目的。该观测系统与常规二维观测系统相比, 可以在不改变观测系统的前提下增强过障碍能力, 还可通过变线元处理为资料解释提供多种不同覆盖次数的剖面。

Line segment subdivision is a new 2-D layout that is developed on the ground of 3-D bin theory. Line segment could be divided if shot point is deployed appropriately. Comparing with conventional 2-D layouts, this layout is capable of crossing barriers. By proper adjustment of line unit, sections of various folds could be generated. This layout is favorable for complicated areas with low exploration degree.
