This paper deals with the problem of estimating of the number of coherent narrowband signals impinging on the L-shaped sensor array, which is composed of two uniform linear arrays (ULAs) connected orthogonally at the one end of each ULA. An efficient detection method is proposed for the incident signals without the computationally burdensome(More)
The present paper analyzes the impact of mechanical shutter on the spectral image acquisition and processing of large-array filter-type multispectral imaging system. The final image quality relies highly on the mechanical shutter due to the fluctuation at exposure time. The conventional mechanical shutter's structure and driving method was analyzed to find(More)
