A large body of work exists concerning uncertainty in ocean current measuring high-frequency radar (HFR) systems. This study investigates the magnitude of uncertainty present in a HFR system in the lower Chesapeake Bay region of Virginia. A method of assessing the fundamental performance of the HFR is comparing the radial velocities measured by two facing HF radars at the centre point of their baseline...
We propose a time-variant regularization in affine projection algorithms, where we update the regularization parameter with a gradient method using a momentum term parametrized by a momentum rate. To further improve the convergence properties of the algorithm in transient stages while ensuring a small final misadjustment, we adaptively estimate the momentum parameter. Then, we prove both the weak...
