多目标混沌MIMO雷达的模糊函数研究

Mutiple Targets Ambiguity Function of Chaotic MIMO Radar

将混沌信号作为MIMO雷达的正交信号,以均匀线阵布阵,对多个目标的混沌MIMO雷达的模糊函数进行了研究,给出了MIMO雷达模糊函数的表达式,并进行了计算机仿真,结果表明:混沌MIMO模糊函数对时延及多普勒频移不同的目标能够进行分辨,具有较高的目标定位能力和距离分辨力.

In this paper,first,the chaotic signals are used as the orthogonal MIMO radar signals to uniform linear array,and then multiple targets MIMO radar ambiguity function is studied,including the expression of ambiguity function,at last computer simulation is carried out.The results show： Chaotic MIMO can carry out to distinguish the different targets of different time delay and Doppler frequency shift,having the higher targeting ability and range resolution.
