体目标垂直尺度估计试验研究

Experimental on Vertical Scale Estimation of Real targets

摘要:

垂直尺度特征是水下航行体目标区别于常规尺度模拟目标的重要特征，文章针对小孔径基阵目标尺度估计需求，提出了一种体目标垂直尺度估计方法，通过实测的水下航行体缩比模型高频回波测试数据进行垂直尺度估计，结果表明能够通过小孔径基阵实现对水中航行体的尺度特征进行有效估计，并且发射信号的形式变化会有不同的特征表征结果，实验初步验证了方法的有效性。

Abstract:

Vertical scale feature is the important feature to distinguish underwater real target and conventional scale simulation target. This paper aims at the requirements of target scale estimation of small aperture array, propose a method for estimating the vertical scale of real targets. Through the measured high frequency echo test data of underwater vehicle scale model to estimates vertical scale. The results show that the scale feature of underwater real target can be estimated effectively through small aperture array, and the form of the transmitted signal changes will have different feature of the representation results. The experimental results show that the method is effective.
