Transmit/Receive Beamforming and Interferences Cancellation Using Phased Mimo Radar with Full Waveform Diversity

APhased MIMO radar with full waveform diversity is proposed which divides the transmit array into overlapping subarrays in such a way that the number of subarrays are equal to the number of transmit antennas. Each subarray send sout a unique wave form towards the target of interest and thus provides a full waveform diversity, which results in the virtual extension of received array. This virtual extension in received array along with the directional beams at the trans mitter side provides some useful results by matched filtering for each waveform. The proposed Full Waveform Diverse Phased MIMO (FWD-PMIMO) radar not only provides some directional gain like a Phased array radar (PAR) but also provides the waveform diversity equivalent to that of MIMO radar. It has the capability of cancelling all the interferences like MIMO radar and can cancel more interferences then the phased array and the Phased MIMO radar.Finally its signal to interference plus noise ratio (SINR) is better than the three radars. The simulation results also exhibits the better performance of proposed radar compared to phased array radar, MIMO radar and phased MIMO radar.
