摘要：A method of acquiring a signal in a high dynamic environment includes
generating a first set of acquired signal power values, the first set comprising an acquired
signal power value for each Doppler bin in a plurality of Doppler bins over a first
predetection integration time (PIT) interval for processing a digital signal, and generatinga second set of acquired signal power values, the second set comprising an acquiredsignal power value for each Doppler bin in the plurality of Doppler bins over a secondsubsequent predetection integration time (PIT) interval for processing the digital signal.The first and the second sets are used to generate at least three additional sets ofacquired signal power values. A new set of acquired power values is generated by
selecting the maximum of the summations for each Doppler bin from the three additionalsets, and a Doppler shift is identified from the Doppler bin having the maximumsummation value that is greater than a threshold value. The output of this method maybe used to initialize a first and a second extended Kalman filters for tracking a carriersignal and a code signal, respectively.
