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。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.
