Embodiments of a device and a frequency data extrapolator are generally described herein. The frequency data extrapolator may receive input frequency data mapped to a two-dimensional frequency grid. As an example, the input frequency data may be based on return signals received, at a sensor of the device, in response to pulsed transmissions of the sensor in a physical environment. Regions of the frequency grid may be classified as high fidelity or low fidelity. A group of basis rectangles may be determined within the high fidelity regions. A column-wise extrapolation matrix and a row-wise extrapolation matrix may be determined based on the input frequency data of the basis rectangles. The input frequency data of the high fidelity regions may be extrapolated to replace the input frequency data of the low fidelity regions.

Device and method of multi-dimensional frequency domain extrapolation of sensor data

Traditional multi-pass radar techniques are not suitable for missions in which the aerial platform both identifies and prosecutes the target at termination of a single pass. A single pass method running a Barankin Estimator provides target height and variance for 3D target imaging that is suitable for war fighters, missiles, UAV, and other aerial platforms capable of nonlinear flight paths.
