MIMO Radar Waveform Design with Robust Interference Suppression Capability

This work considers MIMO radar waveform design with robust interference suppression capability in scenarios where signal is independent to interference. The caused design is a quadratic optimization problem by designing a transmit beampattern with deep radiation notches in the selected directions, under the CM constraint. Then, we propose a novel Riemannian Trust Region (RTR) method on the complex circle manifold for solving this problem with relatively cheap computational cost. Numerical results show our method has better performance compared with current methods.
