中文摘要：
为了获得低旁瓣的MIMO雷达发射方向图，该文提出一种新的最小化峰值旁瓣或积分旁瓣的MIMO雷达方向图优化算法。由于最小化峰值旁瓣或积分旁瓣的优化问题为非凸问题，该算法通过两步来得到此非凸优化问题的全局最优解。第1步通过对发射总功率的约束进行松弛，将原问题转变为一个凸优化问题，第2步则将第1步得到的解进行尺度变换使其满足发射总功率的约束，从而得到原问题的全局最优解。仿真实验表明了该算法相比于已有算法可以获得更低的峰值旁瓣或更低的积分旁瓣。
英文摘要：
To deal with low sidelobe transmit pattern design problem for MIMO radar, a new minimum peak-sidelobe or integrated-sidelobe transmit pattern optimization algorithm is proposed in this paper. Due to the optimization problem of minimizing peak-sidelobe or integrated-sidelobe is non-convex, it is solved in two steps by the proposed algorithm. A convex problem is solved in the first step, and in the second step, the global optimum of original problem is attained by scale transformation of the solution in the first step. The simulations show that the transmit pattern have lower peak-sidelobe or integrated-sidelobe with this algorithm than existed algorithm.
