摘要
Current methods of subbottom sounding use low frequencies for penetration with the subsequent degradation of beam width such that large horizontal areas at the bottom are illuminated. A description is given of a method of subbotom surveying at medium frequencies, 12 kHz, with good penetration and narrow beam width by using a parabolic reflector. Design criteria for the surveyor along with the resultant data obtained from experiments performed at Lake Winnipesaukee, New Hampshire are presented.
