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.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 is an important feature to distinguish underwater real target from conventional scale simulation target.Aiming at the requirements of target scale estimation for small aperture array,a vertical scale estimation method for real targets is proposed.Vertical scale estimation is carried through the measured high frequency echo test data of the underwater vehicle scale model.The results show that the scale feature of the underwater real target can be estimated effectively through small aperture array,and different transmitted signals have different feature results.The experimental results show that the method is effective.
