Abstract:

The purpose of this study was to investigate methods for improving the performance of the phase-locked loop receiver, particularly as a reliable means for locking onto, and determining precisely, the doppler frequency shift of a 2-gc carrier in the presence of noise. The following subjects are discussed in detail adaptive phase-lock theory, receiver description, optimization of phase-locked loop lock-on, interference to a tracking loop from an unwanted carrier with limiting, and doppler loop threshold
