摘　　要：根据多波束测深仪的声纳方程,提出多波束测深仪有效扇面宽度概算方法。通过多波束测深仪声学设计原理估计多波束测深仪的声学参数。分别对各波束的目标强度和声源级进行估算,给出了不同工作深度和工作脉宽情况下的各波束声源级分布,通过检索各波束的声源级确定多波束测深仪的有效扇面宽度,并对测船的选择提出建议。A new method is proposed to estimate the valid fan coverage of multibeam echo sounder based on sonar equation. Acoustic parameters of echo sounder are given by sonar equation based on design principle. Source levels in different depth and pulse width are calculated through TS and SL estimation. The valid fan coverage in different depth and pulse width are given by query. Several suggestions about survey vessels are discussed finally.
