| 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).

| Abstract: | 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 sim... |
