By synthesizing theories of systems engineering, science of talent, talent assessment, performance appraisal and bibliometrics, the author analyzes the qualification structure and performance structure of theachers in military academies and sets up a basic structure and concrete appraisal indicator system of qualifications of technical specialty for teachers in colleges. The author puts forward new appraisal indicators such as "lecuring hours coefficient","republication coefficient","thesis of core journals coefficient" and "citation coefficient". Comparatively complete quantification approaches are invented by the author for working performance of teaching, researching and social service of teachers. Based on this, the author establishes an integrated method to generate the appraisal results. By the application of stadardized processing on the appraisal results and synthetization of weighted indexes, the author solves the addibility and comparability problems of differentiated appraisal results by category or dimensiok, and realizes the amalgamation and comprehensive appraisal of inflexible appraisalresults and flexible appraisal results, and probes into the testification methods of validity, consistency and sensitivity analysis for the indicators system.

A novel direction of arrival and polarization estimation of electromagnetic vector sensors mounted on the airframe is proposed based on biquaternion. The signal processing model for EM-sensor mounted on the airframe is made by biquaternion and then the eigenvalue decomposition of spectral matrix is obtained by means of the EVD of its quaternion adjoint matrix. The memory requirement for data is reduced, and more accurate estimation result is gotten by deducing the stronger orthogonality constraint between the sin- gal and noise subspaces on the field of biquaternion. The performance of the new algorithm is confirmed through numerical examples.

针对机载电磁矢量传感器阵列DOA和极化参数估计问题，提出了一种基于复四元数估计方法，该算法利用四元数建立机载电磁矢量传感器阵列信号处理模型，然后利用四元数联合矩阵的特征分解得到阵列数据相关矩阵的特征分解，一方面使得计算过程中数据的贮存量大大减少，另一方面通过推导得到信号子空间和噪声子空间在四元数域上的正交性从而使DOA和极化参数佑计的精度更高，仿真证实了本算法的有效性。
