摘要：A method of acquiring a signal includes generating a first set of acquired signal
power values comprising an acquired signal power value for each of a plurality ofDoppler bins over a first predetection integration time (PIT) interval, and generating asecond set of acquired signal power values comprising an acquired signal power value foreach of the plurality of Doppler bins over a second subsequent PIT interval. The first andthe second sets are used to generate at least three additional sets of acquired signalpower values. A new set is generated by selecting the maximum of the summations foreach Doppler bin from the three additional sets, and a Doppler shift is identified from theDoppler bin having the maximum summation value. The output may be used to initialize afirst and a second extended Kalman filters for tracking a carrier signal and a code signal,respectively.
