| 摘 要： | 研究双基地多输入多输出（multiple input multiple output, MIMO）雷达目标跟踪的性能。建立双基地MIMO雷达发射相干脉冲串时的目标跟踪数学模型，给出反映目标跟踪性能的贝叶斯克拉美罗界（Bayesian Cramer-Rao bound, BCRB）递推式。针对目标的线性状态方程和双基地MIMO雷达的量测方程，求解BCRB的递推式。最后仿真分析各参数对跟踪性能的影响，结果表明量测信噪比越大、量测脉冲数越多、阵元间距越大跟踪性能越好，且在总发射功率一定的条件下，发射阵元数越多跟踪性能越好。

| Abstract: | The target tracking performance is studied in bistatic multiple input multiple output(MIMO) radar which transmits coherent pulses.The mathematical model of target tracking is constructed,and the recursion formula of Bayesian Cramer-Rao bound(BCRB) which can reflect the tracking performance is given for bistatic MIMO radar.Then the recursion formula is calculated based on the linear state equation of targets and the measure equation of bistatic MIMO radar.The influences of some parameters on the tracking per... |
