英文摘要： The micro-Doppler (m-D) effect can be regarded as a unique movement signature of a radar object. It can provide important features information for the target identification and is a hotpot in the field of automatic target recognition in recent years. And the resource-optimal scheduling technique is one of the most critical techniques of the multifunction phased array radar and the cognitive radar. In the project, the cognitive theory is introduced into the researches on m-D effect and then the cognitive extraction methods of radar target's m-D features based on the resource-optimal scheduling will be developed. The complementary relationships between the radar resource-optimal scheduling and the m-D feature extraction can be established by breaking through some of key problems in the research contents, such as the parameterized expression of radar target's m-D signatures based on the resource-optimal scheduling, the extraction methods of m-D features and the methods of radar resource-optimal scheduling based on the m-D features. The purposes of the project are to extend the application areas of the m-D theory, to develop the cognitive radar theories and to improve the flexibility and adaptive-to-target ability of radar. The development and the prospective achievements of the project have important theory signifi
