| 摘 要： | 研究了分布式多入多出(MIMO)雷达相干信号处理时的横向与纵向分辨能力。利用抛物线拟合法计算模糊函数在横、纵两个方向上切割图形的主瓣宽度,进而推导出该类型雷达横向和纵向分辨率的数学表达式。通过对表达式的分析,讨论了影响分布式MIMO雷达二维分辨率的因素,得到一些系统设计和阵列布置的准则。最后通过仿真验证了分辨率数学表达式和理论分析结果的正确性。

| Abstract: | The horizontal and vertical resolution of distributed multijnput multi-output(MIMO) radar with coherent processing is studied.The parabolic fitting is used to calculate the mainlobe width of the horizontal and vertical cut of the ambiguity function.Then the mathematical expression for the horizontal and vertical resolution of distributed MIMO radar is deduced.By study on the mathematical expression,the factors that affect the resolution of distributed MIMO radar are investigated,and some guidelines on system design and array design are derived.Finally,the simulations are performed to verify the mathematical expression and theoretical analysis. |
