In this paper, the authors consider the joint estimation of Direction-Of-Departure (DOD) and Direction-Of-Arrival (DOA) information of maneuvering targets in a bistatic Multiple-Input Multiple-Output (MIMO) radar system that exploits Spatial Time-Frequency Distribution (STFD). STFD has been found useful in solving various array processing problems, such as direction finding and blind source separation, where non-stationary signals with time-varying spectral characteristics are encountered. The STFD approach to array processing has been primarily limited to conventional problems for passive radar platform that deals with signal arrivals, while its use in a MIMO radar configuration has received much less attention.
