What is angular resolution?

Angular resolution is a property of a receive transducer array and its associated beamformer. Angular resolution is the ability to discern objects at different angles. This is important in separating objects from each other. In general, traditional signal processing techniques are able to generate angular resolutions of approximately 50/L where L is the array's length in wavelengths. FarSounder is able to generate angular resolutions one to two orders of magnitude better through the use of proprietary processing algorithms.
