摘要：
In this paper, we consider unimodular waveform optimization for MIMO radar transmit beamforming with prior information on the directions of target and interferences. A phase-only conjugate gradient method is presented to optimize the unimodular waveform by maximizing the ratio of power at the target location to the power at the interference locations. Simulations show that the transmit beampattern obtained from the optimized waveform achieves a coherent gain of the target location while minimizing the radiation powers around the interference locations.
