摘要
针对低空声目标探测需求,提出了一种利用立体圆锥阵的探测方法。首先推导了目标定距和测向所需的计算公式,其次分析了目标距离、立体阵高度、时延测量误差等对定位和定向性能的影响,最后为立体圆锥阵的工程设计提供了建议。
To satisfy the urgent needs for detecting low altitude acoustic target, a detecting method using taper array is proposed. Firstly, the formula for position is deduced. Successively, the error analysis of target position and directional angle is analyzed for different impact factors, such as the range between target and the taper array, the height of the taper array, the precision of time delay. At last, the proposal of engineering design for taper array is given.
