Coherent processing interval

WebHomepage MIT Lincoln Laboratory WebApr 8, 2024 · Coherence is a statistical measure that shows the degree that two ergodic signals are related through a linear process (non-linearities and additional noise sources will decrease coherence). It is a real quantity with values between 0 and 1 (where 1 means one signal can be completely established from the other through a linear filter).

WebIn its coherent modes, these late-arriving returns perturb the signal processor and may generate false detections. A common technique used to lessen the effects of multiple-interval clutter is to process only the later pulses in the processing interval, that is, some number of pulses are transmitted before search processing be- gins. 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. driver for brother mfc l3750cdw https://dvbattery.com
