Abstract
Systems, methods, and computer program products for sinusoidal nulling are provided. Aspects include transmitting, by a controller, an excitation signal to a first sensor, determining, by the controller, a target harmonic based at least on one or more characteristics of the excitation signal, receiving a return signal from the first sensor, sampling the return signal at a first sample rate based on the target harmonic, and adjusting a phase of the sampled return signal to null the target harmonic amplitude to form an adjusted return signal.
