| 阵形畸变对双线阵左右舷分辨的影响及其纠正 |
| Effect of shape distortion on left-right discrimination of towed twin-line array and its correction |
| |
| 中文摘要: |
| 双线阵左右舷分辨是利用两个单线阵的波束输出信号进行时延估计,根据时延值的符号判断目标所处的左右舷。当双线阵发生畸变时,特定情况下左右舷结果发生变化。本文对该现象进行了分析,并同时给出了一种修正补偿方法。最后通过对试验数据的处理证明了方法的有效性。 |
| 英文摘要: |
| Left-right discrimination of towed twin-line array is realized by discernment of the sign of time-delay value,which is the time diffence of the beaming output signal of two line arrays.As the shape of twin-line array is distorted,the left-right deciding ability can be deformed in special condition.The phenomena is analysed and a correcting method is presented.Experimental results prove that the method is effective. |
