Methods and apparatus for an antenna assembly including one or more array blocks having one or more corporate manifolds, each having an input port, a plurality of output ports, and a plurality of phase shifters, each of the phase shifters located at a respective one of the output ports. Array blocks can further include a plurality of serial manifolds each having an input port and a plurality of output ports, the input port coupled to a respective output port of one of the corporate manifolds; and plurality of antenna elements coupled to respective output port of one of the serial manifolds.

Electronically scanned array using manifolds

An array antenna including two interleaved array antennas, capable of being operated independently at a first frequency, or together, at a second frequency. Each of the two array antennas is composed of alternating elements of an antenna array, and the two arrays are interleaved. Each of the interleaved arrays may be operated independently, e.g., in the X band, or the arrays may be driven together, as a single array with more densely spaced elements, e.g., in the Ku band.

A subterranean radar array system and method for imaging a subterranean target area. In one example, the subterranean radar array includes a plurality of radar chains disposed in a plurality of underground columns, each radar chain including a plurality of radar units forming the plurality of radar chains and at least one processor coupled to a corresponding at least one of the plurality of radar chains and configured to generate an image of a subterranean target area from signals received from the at least one radar chain.

Subterranean radar system and method

A method of generating an image comprises accessing a dataset gathered from a sensor system and generating, from the dataset, a first image including a plurality of image elements. The method further includes generating a training image by combining the dataset with known sensor responses and generating a weighting factor by correcting the training image in view of the known sensor responses. The method further includes applying the weighting factor to one of the plurality of image elements to form a weighted image element.

Systems and methods for image sharpening

A method and system for detecting and localizing damage on a radome. In one example, the system includes a detection mesh made up of an arrangement of conductive wires integral with the radome structure, and a digital strobe circuit coupled to the detection mesh that measures the detection mesh and reports results. In one example, the system includes a controller coupled to the strobe circuit and configured to assess the results and localize the damage based on measured changes in impedance of individual wires within the detection mesh. The controller may be further configured to provide a damage report to a user interface, the damage report optionally identifying the damaged area(s) of the radome.

According to one embodiment, a radar includes multiple antenna elements coupled to an image processing application. The antenna elements have a differing vertical spatial separation relative to one another and are configured to transmit a radio-frequency signal toward a stationary object and receive multiple reflected radio-frequency signals from one or more internal features of the building. The image processing application receives the reflected radio-frequency signals as the antenna elements are moved horizontally with respect to the stationary object. From these reflected radio-frequency signals, the image processing application generates imagery of the stationary object according to phase variations in the plurality of received radio-frequency signals. The imagery depicting vertical characteristics of the one or more internal features of the building.
