Abstract
A multiple input multiple output imaging array for incident angle resolved images with respect to a device under test is provided. The multiple input multiple output imaging array comprises a redundant array of transmit and receive antennas and a controller. In this context, the controller is configured to implement a selection scheme, wherein the selection scheme selects the respective transmit and receive antenna pairs used to create the corresponding image.

A multiple input multiple output millimeter wave imaging array for incident angle dependent millimeter wave images with respect to a device, the multiple input multiple output millimeter wave imaging array comprising:
- a redundant array of transmit and receive millimeter wave antennas, and
- a controller,
- wherein the controller is configured to implement a selection scheme, wherein the selection scheme selects respective transmit and receive millimeter wave antenna pairs for creating a corresponding millimeter wave image,
- wherein the redundant array is redundant with respect to one dimension, and
- wherein the device and/or the redundant array is mechanically moved to create a synthetic two-dimensional redundant array over time.
A multiple input multiple output millimeter wave imaging method for incident angle dependent millimeter wave images with respect to a device, the multiple input multiple output millimeter wave imaging method comprising the steps of:
- providing a redundant array of transmit and receive millimeter wave antennas, and
- implementing a selection scheme,
- wherein the selection scheme selects respective transmit and receive millimeter wave antenna pairs for creating a corresponding millimeter wave image, and
- wherein the method further comprises the step of forming an array creating a distortion and/or alias minimized image with the aid of a collection of the respective transmit and receive millimeter wave antenna pairs.
