Efficient waveform covariance matrix design and antenna selection for MIMO radar

Controlling the radar beam-pattern by optimizing transmit covariance matrix is a well-established approach for performance enhancement in multiple-input-multiple-output (MIMO) radars. In this paper, we investigate joint optimization of waveform and antenna position vector MIMO system to approximate given beam-pattern, as well minimize cross-correlation between probing signals at number target locations. We formulate design task non-convex problem then propose cyclic efficiently its solution. further local binary search algorithm order corresponding positions. show that proposed method can be extended more general case approximating using minimal antennas their Our numerical investigations demonstrate great both terms accuracy computational complexity, making framework good candidate usage real-time processing applications such beamforming aerial drones are motion.
