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CA2CFAR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CA2CFAR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。
Multiple-input multiple-output (MIMO) radar is a new radar technology that has emerged in recent years and is also the focus of research in the radar field in recent years. The signal model of MIMO radar is established. The analytic expression of detection probability and false alarm probability for CA2CFAR detection in MIMO radar is given. The detection performance of CA2CFAR in the background of uniform clutter is analyzed and compared. Simulation results show. MIMO radar has better detection performance for complex targets with similar noise characteristics.
