| 摘 要： | 针对宽带雷达目标识别波形优化中多类目标方位和初相不确定问题，在高斯色噪声背景下提出一种基于凸优化的波形优化方法。该算法通过半正定松弛方法对目标识剐波形优化这个非凸问题进行近似求解，较好地解决了多类目标方位和初相不确定情况下的波形优化问题。仿真结果表明：该方法可以有效增加各类目标之间的可分性，从而提高目标识别性能。

| Abstract: | Aiming at the waveform design problem of broadband radar for the aspect and initial phase uncertainty in target recognition,a novel method of waveform design for target recognition is proposed.It is based on convex optimization in the presence of additive Gaussian colored noise(AGCN).Using semi-definite programming relaxation method,an approximate solution of non-convex waveform optimization is obtained.The experimental results prove the efficiency of the proposed method.Compared to the available approaches... |
