Multiple-input multiple-output (MIMO) radar as a new radar system is proposed at the beginning of 21st century

which has been attracting much attention of researchers and institutions all over the world.In this paper

MIMO radar theory is summarized based on the current literature firstly.Then

the potential capabilities of system configuration

signal design

target detection

parameter estimation and high resolution performance are introduced.At the same time

the restricting factors in practical application are pointed out.Finally

some further work and the technical difficulties in MIMO radar are predicted.
