英文摘要：

An adaptive detection method in partially homogeneous environments is addressed. Firstly, two approaches for the transmitted waveform design are proposed. Secondly, the adaptive polarization diversity and waveform design optimization algorithm based on adaptive subspace detector （ASD） is proposed, which makes the optimization detection issue transform into a multiple parameters optimization problem. Thirdly, the Taguchi optimization algorithm is used to solve this problem. Experiment results indicate that further improvement in detection performance can be achieved by the proposed method. Most importantly, the proposed method has high efficiency because of using the Taguchi optimization algorithm.
