一、绪言1963年夏,拉蒙特研究所对SSQ-28、SSQ-41型声纳浮标进行了首次试验。通过试验并没有获得理想的资料,但其确有发展前途。在船上应用定向接收天线(接收遥测检波器通过浮标的输出)大大改进了这种技术,使接收范围大约增加到40公里。利用气动声源(气枪)每12至15秒放炮获得了极好的资料密度。从1966年起,在拉蒙特调查船上装上了声纳浮标装置,并常规用以测定沉积物速度。在此期间也研究出了求取精确层速度的计算机程序。在前一篇报告中阐述了船上采集资料的详情和计算过程,关于声纳浮标资料的整理和校正是根据其本身工作期间记录到的垂直反射剖面的记
I. INTRODUCTION In the summer of 1963, the Lamont Institute conducted its first test of the SSQ-28 and SSQ-41 sonobuoys. Pass the test did not get the desired information, but it does have a promising future. The use of a directional receiving antenna (receiving the output of a telemetry detector via a buoy) on board has greatly improved this technique, increasing the reception range to 40 km. The use of pneumatic sound source (air gun) shot every 12 to 15 seconds to obtain excellent data density. Since 1966, a sonar buoy has been installed on the Lamont survey vessel and is routinely used to determine sediment velocity. During this period also developed a computer program to obtain the exact velocity layer. In the previous report, details and calculations of the data collected on board were elaborated. The collation and correction of sonobuoy data was based on the records of vertical reflection profiles recorded during its own operation
