一种基于模型的雷达超分辨方法

基于多目标及其雷达回波信号的建模，本文提出了一种实现雷达超分辨的新方法．该方法的基本思想是将空间上相距很近的多个目标的分辨转化为目标冲激响应的辨识，然后利用最小二乘法估计目标的冲激响应函数．文中还提出了距离分辨概率的概念，给出了其定义．仿真结果表明，新的超分辨方法是十分有效的，井且具有结构简单和分辨力高等特点．

A Modeling-Based Radar Superresolution Approach

On the basis of modeling of multiple targets and radar returning signals, a new method for radar range superresolution is introduced in this paper. This method tums the resolution of multiple closely spaced targets into an identification of the target impulse response functions. The least-square (LS) method is then used to estimate impulse resoonse functions of the targets. The concept of radar range resolution probability is also introduced.It is shown from the simulation results that the new superresolution method is much efficient, and has advantages such as having a simple structure, as well as high resolution.
