Transmit beampattern design based on convex optimization for MIMO radar systems
We propose two algorithms based on convex optimization technique for the synthesis of the waveform covariance matrix in order to approximate a desired transmit beampattern in MIMO radar systems. In the first algorithm, an omnidirectional beampattern design is proposed to synthesize the covariance matrix. The second algorithm is proposed to guarantee the distortionless response in the mainlobes domain and maintain the sidelobes to be lower than the given threshold values. These optimal designs are converted to the Second-Order Cone Programming and are solved via the convex optimization toolbox CVX. Numerical examples demonstrate the performance advantage of our algorithms.
