The Chirp acoustic subbottom profile system based on the linear frequency modulation technology can solve two most important problems of geologic investigation in water areas,namely,depth and resolution.This system consists of five parts:navigation system,signal control system,transmission system,signal receiving system and depth sounding system.The vertical resolution of the system is about 15cm and the maximum investigation depth is about 100m,both depending on the characteristics of stratum and water.Considering the specificity and complexity of the system,the key operation was introduced in details.Furthermore,applications of the system in active fault exploration,pipeline direction exploration and riprap exploration were presented in this paper.The results show that this acoustic subbottom profile system is available in shallow strata and structure investigation.
