Comparisons of anti-jamming property of array configurations for MIMO radar with the same virtual array

Abstract

The comparisons of anti-jamming of array configurations for MIMO radar with the same virtual array is made. It is found that the degrees of freedom of clutter are same for the array configurations which have the same virtual array when there' s no jammer exist. If there are jammers exist, the clutter rank vary much depending on the numbers of transmitter, receiver no matter the transmitting array is set to be sparse configuration or receiving array is set to be sparse configuration. With the help of this conclusion, we can design an optimal array configuration when there are jammers which usually exist..
