Multitarget can be distinguished by Capon method as well as the targets angles with respect to transmitter and receiver can be synthesized using the received signals. Thus the locations of the multiple targets are obtained and spatial synchronization problem in traditional bistatic radars is avoided. The maximum number of targets that can be uniquely identified by proposed method is also analyzed. It is indicated that the product of the numbers of receive and transmit elements minus-one targets can be identified by exploiting the fluctuating of the radar cross section RCS of the targets. Cramer-Rao bounds CRB are derived to obtain more insights of this scheme. Simulation results demonstrate the performances of the proposed method using Swerling II target model in various scenarios.

INTRODUCTION Multiple-input multiple-output MIMO radar has been recently become a hot research area for its potential advantages. MIMO radar uses multiple antennas to simultaneously transmit several independent waveforms and exploit multiple antennas to receive the reflected signals. The echo signals are independent of each .
