单矢量水听器可以对单目标进行俯仰角的测量,当出现多目标时会使得俯仰角测量结果出现误差,文章通过理论推导给出了多目标情况下对俯仰角测量的影响.结果表明,当出现多目标时,尽管在两目标俯仰角相同的情况下,利用传统的俯仰角测量公式测得的结果仍是错误的,测量结果会比实际俯仰角值大.当两目标俯仰角不同时,测得的俯仰角结果也并不像水平方位角那样是合成方位,测得的俯仰角值可能大于两目标任意俯仰角值,具体值则跟两目标的水平方位夹角有关. 最后,通过仿真和实验对上述分析结果进行了验证.

A single vector hydrophone can be used to measure the single target elevation angle. When mul-ti-targets appear, the results of the elevation angles will have some error. This paper presents the influence of the multi-targets on the elevation angle measurement theoretically. The conclusion shows that the mea-surements using the conventional formula are wrong when the multi-targets appear in the same elevation angle. The measurement results will be larger than the actual elevation angle. When the elevation angle of the targets are not same, the measured elevation angles are not the azimuth angle obtained by the synthetic angle of the multi-targets. The measured values may be greater than each elevation angle and have relation with the angle of multi-targets azimuth angles. Finally, the results of the above are testified by simulation and experiment.
