五 ANVIT——速度谱程序程序原理 ANVIT是用共反射点道集记录作输入制作速度谱的。制作过程中用的是变速扫描的方法,即根据事先给定的一条参考速度曲线,围绕这个参考曲线取等ΔT增量的24条扫描曲线,它们包含了该地区全部可能存在的速度。用这24条扫描曲线进行动校正、迭加,形成迭加谱矩阵,最后加工显示输出。程序框图见图12。参数的填写 1—7列 *ANVIT 9—10列第一选件空:只输出矩阵,作为ANVIR或ANVIL的输入 P:速度谱的炮点选件
ANVIT - speed spectrum program procedures ANVIT is the total reflection point gathers record as input speed spectrum. A variable-speed scanning method was used in the production process. According to a given reference speed curve, 24 scanning curves of ΔT increments around this reference curve were included, which contained all the possible speeds in the area. With these 24 scanning curves for dynamic correction, superposition, the formation of superimposed spectrum matrix, the final display processing output. Block diagram shown in Figure 12. Fill in parameters 1-7 Columns * ANVIT Columns 9-10 First Option Empty: Output Matrix only, as input for ANVIR or ANVIL P: Gunpoint Option for Speed Spectrum
