Coherent integration time
WebThe coherent pre-filter and non-coherent pre-filter have complementary characteristics, which can be used to design a hybrid pre-filter structure [].An adaptive hybrid coherent/non-coherent GNSS vector tracking loop has been proposed to adaptively switch the pre-filter type that is working in tracking channel according to the signal strength []. ... WebHowever, coherent integration might not always be possible due to the target's RCS fluctuation, which can make the coherent processing interval (CPI) too short to collect enough samples. Noncoherent integration discards the phase information and combines the squared magnitudes (assuming the square-law detector) of the signal samples instead.

WebMar 19, 2024 · However, to improve the tracking sensitivity further, increasing the coherent integration time is necessary, but it is typically limited by the navigation data bit sign transition. Moreover, for standard KF-based tracking receivers, the KF parameters are initialized by the acquired results. WebCoherent Processing Interval. The CPI is 12seconds, so that it is long enough to observe some periods of the wanted slow signal (the period of the sinusoidal motion is …
WebFeb 1, 2013 · The idea is to do coherent accumulation of each chip of an unknown signal during a rather long time interval. The interval may be as long as a full satellite pass; for medium Earth orbits, this could be up to six hours. One of the receiver’s channels is configured in the same way as for signal tracking. WebDec 9, 2010 · The choice of integration time is determined by a number of factors, though there are usually practical reasons for choosing a minimum integration time. For example, for the GPS C/A code, a minimum integration time of 1 ms is usually chosen to ensure sufficient inter-satellite signal separation.
