噪声干扰器最佳布放位置与深度研究

基于简正波理论，利用宽带信号的频域分解与合成求解噪声信号的传播问题。在给定的战场态势和海洋环境下，研究了噪声干扰器的对潜开角、对潜距离、布放深度参量对干扰效果的影响，得到了在远场条件下，噪声干扰器的布放深度对干扰效果的影响要大于其对潜距离的影响结论。而在之前的研究中深度参量的影响一直是被忽略的。在此基础上，通过进一步计算得到了噪声干扰器的最佳布放位置和深度。

Research on Optimum Location and Depth of Noise Jammer

The propagation problem of noise signal is solved using the decomposition and synthesis of broadband signals in frequency domain based on normal mode theory. The influences of included angle and distance between submarine and jammer, and the emplacing depth of jammer in given battlefield situation and ocean environment on jamming effect are studied. The result shows that the emplacing depth of jammer has a important influence on the jamming effect in far-field, which was ignored in previous researches. On the basis of the research, the optimum location and depth of noise jammer are obtained via further calculations.
