Abstract :
In this article, the excitation phases of the antenna arrays of MIMO radar are optimized via minimizing the transmit beam power in certain pre-selected directions. A novel algorithm, adopted from the Fletcher´s new variable metric method (VMM), is employed for antenna phase optimization. The simulation results demonstrate the effectiveness of the algorithm.
