WebDec 6, 2024 · In this paper, a novel transmit beampattern optimization method for dynamic coherent radar based on a distributed satellite constellation is presented. Firstly, the effective coherent detection range interval is determined by several influence factors, i.e., coherent detection, far-field, and system link constraints. WebA coherent processing interval (CPI), in radar systems, indicates a group of multiple pulses, usually with the same PRF and frequency. A CPI will generally consist of one or more coherently integrated pulses, and possibly 1 or more fill pulses. PRF and frequency are sometimes changed between CPIs or groups of CPIs. ...
