Recently

it becomes difficult for normal radar system to detect the stealth targets and space objects

so the researchers have paid more attention to the MIMO radar. For moving targets

the probability density function of sufficient statistic is analyzed firstly; then

the meaning of four working mode is discussed; finally

based on four working mode

the MIMO radar system’s detection method and performance are development. By theoretical analysis and simulation

we get the conclusions witch are: MISO working mode is suitable for MIMO radar system

and the number of receive station should be 4~6.
