Research on the Problem of Sample Support in STAP被引量:1
《Chinese Journal of Aeronautics》2001年第4期229-234,共6页王玮 李少洪 毛士艺 
In the airborne radar space-time adaptive processing (STAP), the interference covariance matrix must be estimated from the IID samples which are always limited in practice. Aimed at this problem, this paper studies th...

Multi-Objective Controller Design Using Eigenstructure Assignment Based on LMI
《Chinese Journal of Aeronautics》2001年第1期44-48,共5页孙秀霞 毛剑琴 林岩 
Foundation of National Education Committee of China
A new method of applying linear matrix inequalities (LMIs) to multi-objective eigenstructure assignment is put forward. Since there is always a degree of freedom in eigenstructure assignment using state or output feed...

MODAL PARAMETERS EXTRACTION WITH CROSS CORRELATION FUNCTION AND CROSS POWER SPECTRUM UNDER UNKNOWN EXCITATION被引量:1
《Chinese Journal of Aeronautics》2000年第1期19-23,共5页郑敏 申凡 陈怀海 鲍明 
Item of the 9-th F ive Plan of the Aeronautical Industrial Corporation
In most of real operational conditions only response data are measurable while the actual excitations are unknown, so modal parameter must be extracted only from responses. This paper gives a theoretical formulation f...
