摘　　要：讨论了在综合考虑目标检测与估计性能的条件下,雷达发射波形的优化设计问题。由于衡量目标检测与估计性能的直接指标是信噪比(SNR)和互信息(MI),文中采用将SNR作为约束条件下最大化MI的准则,通过引入发射信号的自相关序列将优化目标转发为凸优化问题,进而优化设计发射波形。仿真实验的结果表明,利用该方法所设计的波形能够满足输出SNR约束(对于目标检测性能)且同时能够最大化MI(对应目标估计性能)。In this paper,we address the optimal radar transmit waveform design problem by combining both the target detection and estimation performance.Considering the target detection and estimation are evaluated by the signal-to-noise（SNR） and mutual information（MI） criteria,we propose a waveform design method that maximizing MI based on the SNR constraint by introducing the autocorrelation sequence of the transmit signal that can make the objective function convert to be a convex optimal problem.The results of simulations demonstrate that the transmit waveform designed by the proposed method can satisfy SNR constraint corresponding to target detection performance and maximize MI corresponding to target estimation performance.
