集中式MIMO雷达与相控阵雷达干扰抑制性能对比

摘要

In order to compare the interference suppression performance between the traditional phased ar-ray radar and colocated multiple-input multiple-output( MIMO) radar,this paper develops the signal to in-terference-noise ratio( SINR) output and improvement factor for colocated MIMO radar and phased array radar in theory. Numerical simulation indicates that colocated MIMO radar has a better interference sup-pression performance through increasing SINR output.%针对传统相控阵雷达与集中式多输入多输出( MIMO)雷达的干扰抑制性能优劣问题，对集中式MIMO雷达与相控阵雷达的信干噪比和改善因子进行了对比分析，从理论上研究了两种体制雷达的干扰抑制能力并进行了数字仿真。仿真结果表明，与传统相控阵雷达相比，集中式MIMO雷达通过提升信干噪比输出增强了干扰抑制能力。
