IMAGING SONAR WITH OPTIMIZED ARRAY STRUCTURE OF RECEIVING TRANSDUCERS CONSIDERING BEAM PATTERN OF TRANSDUCER ELEMENT

摘要

PURPOSE: An imaging sonar with the optimized array structure of receiving sound transducers considering the beam pattern of a sensor is provided to optimize the array structure of the receiving sound transducers in consideration of the beam pattern of the sensor, thereby preventing an aliasing phenomenon even through a frequency is low. CONSTITUTION: If the angle of the location where the size of a beam pattern is 0 is Θ0, the angle of the location where a beam pattern includes the maximum value by an array structure by controlling the array interval of elements which configure a receiving sound transducer is the same as Θ0.
