Radar data processing systems and methods
Techniques to facilitate radar data processing are disclosed. In one example, a radar system includes a frame generation circuit and a frame processing circuit. The frame generation circuit is configured to receive radar signals. The frame generation circuit is further configured to convert the radar signals to at least one frame having a camera interface format. The frame processing circuit is configured to receive the at least one frame via a camera interface. The frame processing circuit is further configured to process the at least one frame. Related methods and devices are also provided.
Visually correlated radar systems and methods
Techniques are disclosed for systems and methods to provide visually correlated radar imagery for mobile structures. A visually correlated radar imagery system includes a radar system, an imaging device, and a logic device configured to communicate with the radar system and imaging device. The radar system is adapted to be mounted to a mobile structure, and the imaging device may include an imager position and/or orientation sensor (IPOS). The logic device is configured to determine a horizontal field of view (FOV) of image data captured by the imaging device and to render radar data that is visually or spatially correlated to the image data based, at least in part, on the determined horizontal FOV. Subsequent user input and/or the sonar data may be used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

Digital radar imaging using 5G-NR millimeter wave base station antenna solutions
A mechanism is provided by which a radar image can be generated using mmWave transmissions from 5G-NR type base station antenna arrays. Base stations in 5G-NR use a beam searching sequence utilizing a defined synchronization signal burst (SSB) during their communication initialization with client devices. Embodiments utilize these SSB signals as a radar “chirp” to build a radar image of the base station surrounding in parallel with the typical 5G-NR communication initialization. Antennas on the base station can receive the reflected signals to define the radar image, in conjunction with correlation and time-management logic to properly associate received reflected signals with original transmitted signals. Such information can be processed by a synthetic aperture radar processing logic to form the radar image.
Systems and Methods for Noninvasive Detection of Impermissible Objects Using Personal Equipment
A system comprises a personal device such as one used by law enforcement, and a housing containing a portable radar system with both a ranging resolution and lateral resolution sufficient to detect an object concealed on a person (e.g., one that operates in the THz range), where the housing is configured to be mounted in contact with the personal device such that when mounted, the combined handheld device and housing have a form factor that allows it to retain its characteristic as a personal device, and where the portable radar system is configured to, when in operation, emit a radar beam and to receive a reflection of the emitted radar beam.
