We have previously proposed a two-dimensional correlation technique capable of measuring target velocities in any direction in the imaging plane and related its performance to the fundamental characteristics of speckle size and speckle decorrelation rates [1]. In this paper we relate the inaccuracy in the measurements to system parameters such as signal-to-noise ratios, correlation coefficients and spatial frequencies and explain how factors such as pulse bandwidth, stationary noise and focal errors can introduce errors in the measurements. We discuss the effect of the anisotropic nature of speckle in the axial and lateral dimensions on the magnitude of errors in the two dimensions.
