摘　　要：从MIMO雷达的特点出发,在双基地雷达模糊函数基础上,提出了MIMO雷达的模糊函数。MIMO雷达的模糊函数是再双基地雷达模糊函数的线性组合,并且双基地雷达的模糊函数是直角坐标系中目标速度和位置的函数。数值计算表明,MIMO雷达的模糊函数具有直接确定目标位置和速度的能力,并且模糊函数与参考点的选取无关,通过增加发射站和接收站的数目能够提高模糊函数的位置分辨率。The MIMO radar ambiguity function of polyphase code is presented based on the ambiguity function of bistatic radar. The MIMO radar ambiguity function is a combination of the ambiguity function of bistatic radar ,which is a function of target coordinate and velocity in right-angle coordinate system. Experimental gives the following conclusions, first, the ambiguity function of MIMO radar can directly determine the position of target and velocity; secondly, the resolution of the position is higher when more transmitters and receivers are used; finally, the ambiguity function of MIMO radar is unrelated with the reference point.
