摘　　要：该文基于Swerling Ⅲ和Swerling Ⅳ目标模型,研究空间分集MIMO(多输入多输出)雷达发射相干脉冲串时的检测方法和性能,得到了检测概率和虚警概率的解析表达式。仿真表明,随着相干脉冲串数目的增加,目标的检测性能更好;同时,与传统雷达相反,在高检测概率时,空间分集MIMO雷达对Swerling Ⅲ型目标的检测性能优于Swerling Ⅳ型目标。The detection performance of spatial diversity Multiple-Input Multiple-Output （MIMO） radar for Swerling Ⅲ and Swerling Ⅳ target is analyzed based on coherent pulses. The false alarm probabilities and detection probabilities are derived analytically. Simulation results demonstrate that MIMO radar can get better detection performance when more coherent pulses are used. In contrast with conventional radar, the detection performance of MIMO radar in Swerling Ⅲ target outperforms Swerling Ⅳ target in high detection probability.
