利用多部雷达不同视角下目标的宽带投影尺寸,可以估计目标的真实尺寸。文中利用投影尺寸为目标轴线投影到雷达视线的长度,建立了多雷达投影尺寸与目标轴线向量的测量方程,并利用Kalman滤波进行迭代求解,再求轴线向量的模值,即得到真实尺寸,从而解决了目标真实尺寸的建模问题。仿真结果表明了该方法的有效性。

The actual target dimension can be estimated by using the wideband projected target dimension in different perspectives of multiple radars. In this paper, the projected target dimension is the length of target axis projection to the radar line of sight, and the measurement equation of the multi-radar projection and the target axis vector is established. The Kalman filer is used to select the generation solution. And then the module of the axis vector is calculated . that is the actual dimension is obtained. Thus the problem of modeling the actual dimension of the target is solved. The method and the simulation results well validate the theoreticalanalysis.
