target noise meaning in English

目标噪声

Because it needs a lot of fund and time to obtain the real data of target noise , there is limited quantity of real data now
由于目标噪声实测信号的获取需要耗费大量的经费和时间，实测数据有限。
In this paper , on the basis of deeply analyzing the spectrum feature of the target noise , a large quantity data of two sorts of target noise are simulated under the condition of different frequency , departure , depth and snr
本文还在深入分析了目标声场谱特征的基础上，分别建立了两类目标在不同频段、不同横距、不同深度及不同信噪比下的大量仿真数据。
The scheme of target recognition based on gray model is set up . gm ( 1 , 1 ) and gm ( 1 , n ) of target noise are also set up . the method of target recognition , which takes gray model parameter as features , is put forward after their models and the characteristic of model parameter are deeply analyzed and researched
设计了基于灰色模型的目标识别方案，分别建立了目标声场通过特性的gm ( 1 ， 1 )模型和gm ( 1 ， n )模型，并对其模型及模型参数的特点进行了深入的分析和研究，提出以灰色模型参数为特征量进行目标识别的方法。
