MIMO雷达和组网雷达的CA-CFAR检测性能比较

摘要

MIMO radar is an emerging technology in recent years and studying MIMO radar is attracting the attention of researchers in recent years. The signal model is presented, the CFAR detectors and analytic expression in detection performance is proposed, and the comparison of CA-CFAR performance for MIMO radar and netted radar is provided. Simulations show that MIMO radar has better detection performance than netted radar for complex noise target.%多输入多输出(MIMO)雷达是近几年出现的一种新雷达技术,也是近几年雷达领域研究的重点.建立MIMO雷达的信号模型,明确给出MIMO雷达进行CA-CFAR检测的检测概率和虚警概率解析表达式,对组网雷达和MIMO雷达在均匀杂波背景下CA-CFAR检测性能进行了分析对比.仿真结果表明.MIMO雷达对类似噪声特性的复杂目标具有更好的检测性能.
