Abstract
Provided is method of signal processing of raw data obtained using a chirp sub-bottom profiler. The method includes transmitting a chirplet (minimum frequency: initial first frequency, maximum frequency: initial second frequency, pulse length: initial pulse length) to survey target strata using a chirp sub-bottom profiler and acquiring raw data reflected and received from a target object, correcting the raw data, generating a comparison chirplet using a sub-bottom reflection signal of the raw data, cross-correlating the corrected raw data with the comparison chirplet to generate a first Klauder wavelet section, auto-correlating the comparison chirplet to generate a second Klauder wavelet, and deriving a physical property of the survey target strata by deconvoluting the first Klauder wavelet section and the second Klauder wavelet.
