Based on those , this paper gives two kinds of improved estimates 5 * and b ( k ) 基于此,本文给出了b的两种改进估计(
The used value of doppler centroid influence the imaging result very much , so it must be estimated precisely . the estimating methods contain time domain method and frequency domain method . time - frequency analysis method can be used to improve estimating precision 多普勒中心频率的取值对成像效果有很大影响,必须精确估计,估计方法有时域方法及频域方法,还可利用时频分析方法提高估计精度是。
In addition to the statistical advantage gained by combining same - source data ( e . g . , obtaining an improved estimate of a physical phenomena via redundant observations ) , the use of multiple types of sensors may increase the accuracy with which a quantity can be observed and characterized 除了同源数据的简单组合(如:通过冗余的观测数据可以获得物理现象的更精确的估计)外,应用不同种类的多传感器也可以提高某些可观测量和可描述量的估计精度
