The proposed detector applies the given steering vector and array structure information to the matrix information geometry detection method so that it can be used for space–time adaptive detection. While improving the detection performance, the matrix information geometry detector's original an...
1) steering vector mismatch 导向矢量失配 1. There are two important factors that affect the performance of Space-Time Adaptive Processing(STAP),that are steering vector mismatch and covariance matrix mismatch. 导向矢量失配和协方差矩阵失配是影响空时自适应处理(STAP)性能的两大主要因素,基于在最差情...
The theoretical covariance matrix is first estimated via the shrinkage method. Subsequently, the desired signal steering vector is estimated based on maximizing array output power under the correlation coefficient constraint and norm constraint. The original nonconvex quadratic programming problem, whose ...

Various chalcidoid wasps can actively steer their terebra (= ovipositor shaft) in diverse directions, despite the lack of terebral intrinsic musculature. To investigate the mechanisms of these bending and rotational movements, we combined microscopical and microtomographical techniques, together with vi...
To develop an adaptive beamformer against the steering vector mismatch of the signal of interest (SOI), a novel robust algorithm is proposed to estimate the steering vector of the SOI and interference- plus-noise covariance matrix (INCM) in an alternative and iterative way. That is, via deter...
