Abstract:

The ability of the phase-locked loop to track a Doppler flyby signal is determined in terms of loop parameters and signal parameters. The signal under consideration is a pure sinusoid transmitted from an object traveling in a straight-line constant-velocity path past a stationary receiver. Loop performance bounds are estimated analytically, and then tested by computer simulation of the nonlinear error equations. Both second and third-order loops are examined, and the region where the third-order loop significantly increases performance as compared to the second-order loop is determined. Author
