In antenna theory, a phased array usually means an electronically scanned array, a computer-controlled array of antennas which creates a beam of radio waves that can be electronically steered to point in different directions without moving the antennas. In a simple array antenna, the radio frequency current from the transmitter is fed to multiple individual antenna elements with the proper phase relationship so that the radio waves from the s… lighthouse denver writersWebSpatial Sampling. Phased arrays consist of multiple array elements. Consider each K-by-N submatrix of the radar data cube. Each column vector consists of K fast-time samples for a single pulse received at a single array element. The N column vectors represent the same pulse sampled across N array elements. peachloveca wholesaleWebApr 10, 2024 · In this paper, we focus on coherent and non-coherent joint processing to achieve beamforming array gain and spatial diversity gain for improvement of detection performance of the traditional phased-array sonar.
