基于点扩展函数，推导出共焦系统的成像公式，模拟了探测器尺寸对分辨率的影响，并提出最佳针孔半径。
The imaging equations are derived based on point spread function, the influence of detector on resolution is simulated, and the optimum pinhole radius is proposed.
采用这种宽孔径成像方法的结果表明，即使对单个共炮点道集也能收到相当好的成像效果。
The use of wide aperture image method even makes single common-shot gather find quite good image result.
然后对该道集进行速度分析、动校正和叠加，得到偏移地震剖面，即共散射点成像。
Then the trace gather undergoes velocity analysis, normal moveout correction and stack to bring seismic migrated section ( This is called scattering point imaging).
