Abstract: A surveillance monitoring method is provided, which includes: executing an algorithm using a camera to perform a first inference on recognition of an obstacle and recognition of a target; tracking at least one object using the camera to generate image information; performing a second inference on recognition of the obstacle and recognition of the target using a radar; tracking the at least one object using the radar to generate radar information; fusing the image information and the radar information to obtain a first recognition result; collecting environmental information using the camera or the radar, and forming a confidence level based on the environmental information, the first inference, and the second inference; and dynamically adjusting a proportion of the image information and the radar information according to the confidence level when fusing the image information and the radar information to obtain a second recognition result.

Abstract: The present disclosure provides a method for performing beamforming. The method includes initiating a first signal transmitted from a target second device to be received by a first device having an antenna array. A first beamforming weight matrix is generated by the first device that automatically corrects amplitude and phase errors of the antenna array and maximizes antenna gain toward the target second device using a covariance matrix derived from the received first signal. An enhanced second beamforming weight matrix is then generated by the first device using a mask window or a jointly optimized algorithm to further suppress interference to and from other active second devices. The enhancement is computed and applied based on the distribution of multiple active second devices. The antenna array is steered using the second beamforming weight matrix to transmit to and receive from the target second device with an optimized antenna beam pattern.
