Abstract
Techniques are disclosed for systems and methods to provide high resolution interpolation of arrival direction of echo return signals using an active mills cross arrangement, such as in sonar or other ranging sensor systems. A system may include an active mills cross arrangement with high resolution interpolation of echo returns in two planes. The active mills cross arrangement may include a transmitter configured to emit one or more signals, a first line array including a first plurality of elements defining a first plane, and a second line array including a second plurality of elements defining a second plane orthogonal to the first plane. At least one of the first line array and the second line array may be configured to receive echo returns of the emitted signals from one or more objects or targets.
