N2 - We jointly design the transmit and receive beamforming based on a-priori information on the locations of target and interferences in an active array, where each transmit element emits the same waveform up to a complex scalar. A sequential optimization algorithm is proposed to maximize the output signal-to-interference-plus-noise ratio (SINR). Numerical results demonstrate that a significant gain in the output SINR can be achieve in this active array, compared to the conventional phased-array radar and omnidirectional multiple-input-multiple-output (MIMO) radar.
