【摘要】 针对目标航行深度未知的水下目标被动定位,提出了基于双圆锥阵列的水下被动定位方法,解决了常规超短基阵无法实现被动目标距离估计的问题。双圆锥阵列是通过上下两个七元圆锥阵组合实现,可完成水下未知航行深度目标的方位角、俯仰角和目标距离的被动估计。仿真证明了该方法的有效性和可行性。更多还原

【Abstract】 To solve the problem that passive location of the underwater target based on double-cone array can not achieve target distance estimation in the case that the target depth is unknown,a underwater passive location method based on double-cone array is proposed.The double-cone array comprised of two seven-element cone arrays can achieve the passive estimation of underwater target azimuth,pitch angle and distance when the target depth is unknown.Simulation shows the effectiveness and feasibility of the method.更多还原
