距离单元 meaning in Chinese
range unit
Examples
- The kernel of this method is the emendation of the across moving range bin , which combines the emendation and the range compression
这种方法的核心是校正越距离单元走动，它是把走动校正跟距离压缩结合起来做。 - Operand of map - drift is large , so 2 ways of reducing the operand are put forward , which are increasing the iterative step and decreasing the numbers of range cells
由于md算法的运算量很大,采用了增加迭代步长、减少距离单元两种减少运算量的方法。 - To the problem of the across moving range bin in high squint dbs , a kind of compensating technique is proposed to improve the resolution of high squint dbs
针对大斜视dbs中的距离单元走动问题，提出了一种补偿技术来提高大斜视时dbs的分辨率的方法。 - This method constructs covariance matrix by utilizing data vectors in different range lines and projects phase error vector into noise sub - space which is formed by eigendecomposing the covariance matrix
该方法利用不同距离单元的观测矢量构造协方差矩阵，然后通过对协方差矩阵特征分解得到噪声子空间，最后将相位误差矢量向噪声子空间投影来估计多普勒调频率。 - In order to simulate the return , a radar coherent video echo model is used to simulate target echo , clutter and noise separately . then the three parts which are in the same range cell are added together to form a matrix to represent return in one radar coherent processing interval ( cpi ) . this matrix is called a frame of range doppler data
为了较为全面地对雷达回波进行仿真,采用相干视频回波模型分别模拟雷达目标回波、杂波和噪声,通过在距离单元内叠加的方法,将一个雷达相干处理周期内的回波数据用一帧距离多普勒平面数据表示。
