Abstract: The basic principle and major steps of amplitude compensation of time?frequency and space domain are presented in this paper.The key of narrow band?pass filter frequency division is how to choose band?pass filter gate with equal band to minimize Gibbs effect and frequency leak among bands. According to the change of median of average root mean square amplitude in each time gate of model shot gathers from shallow to deep, linear equations of ground absorption and attenuation coefficients are derived to get unified amplitude com?pensation coefficient for each frequency band in whole area by using least square method. Except previous compensation, space domain compensation is conducted by counting amplitude attenuation curves of shots in whole area for near?surface explosion effect in different frequency bands. Real data processing effects show that amplitude compensation in time?frequency and space domain is much better in quality than common spherical diffusion and absorption compensation method
