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

WebOct 7, 2024 · A novel coherent integration method for high dynamics direct sequences spread spectrum (DSSS) signal is presented. The presented method is based on adjacent cross-correlation function (ACCF) and Lv's distribution (LVD). ACCF is firstly used to compensate the code phase drift and reduce the Doppler frequency migration order. WebConsidering the low frequency property of the system, a signal processing procedure is proposed involved in long coherent processing interval (CPI) methods. Some crucial … 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. ... driver for brother mfc j825dw printer
