| Abstract: | 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. |
