3 . a novel modular learning strategy is present based on the cross - component in the wvd and neural network for the detection of a target signal of interest in a nonstationary oceanic environmemt and this strategy makes no assumptions on the environmemt . simulations show that this new method has much superiority over matched filter 首次利用wigner - ville分布中的交叉项并结合人工神经网络，提出了一种新的基于模块学习策略的信号检测方法，该方法对淹没在非平稳海洋环境噪声中的目标信号可进行有效地检测，并且这种学习策略没有对环境噪声作任何假设。
