为解决界面倾斜和其它原因对弯线迭加质量的影响,提出弯线倾斜迭加方法。讨论了消除界面倾斜影响的弯线正常时差公式,提出综合利用波的振幅、相位和周期特征的波形迭加方法,从而改进了弯线共面无道集迭加和横向道集扫描迭加质量。横向波形扫描迭加试算结果证明,弯线倾斜迭加方法抗干扰能力强,有利于突出有效波,特别是弱波,是一个有希望的方法。
In order to solve the influence of interface tilt and other reasons on the superposition quality of curve line, a method of superposition of curve line inclination is proposed. This paper discusses the normal time difference formula of curve line which eliminates the effect of interface tilt and proposes a waveform superposition method which can comprehensively utilize the amplitude, phase and periodic characteristics of the wave so as to improve the superposition quality . The transverse waveform scanning superposition trial calculation results prove that the method of oblique line superposition method has strong anti-interference ability, which is good for highlighting effective wave, especially weak wave, which is a promising method.
