A field of awareness (FOA) system provides an operator of a vessel with intuitive object detection and positioning information. The system may comprise an FOA cloud server and an FOA unit. The FOA cloud server may be configured to perform a machine learning training operation to modify an FOA model based on a location-based relationship between training radar data and truth data. The FOA unit may be disposed on the vessel and may comprise processing circuitry configured to apply radar data to the FOA model to perform a comparison to determine a matched model signature, an associated matched object type, and an icon representation for the object of interest. The processing circuitry also be configured to control the display device to render the icon representation of the object at a position relative to a representation of the vessel based on the relative object position.

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.

The method, implemented within a mission system that comprises an electro-optical camera which generates video images, detects movable/moving objects, and tracks a target object; and a radar sensor which generates signals and detects blips, consists of: acquiring a video image provided by the camera and blips provided by the radar sensor at the time instant of generation of the acquired video image; converting the geographic position of each acquired blip, expressed in a first reference frame associated with the radar sensor, into a geographic position expressed in a second reference frame associated with a camera pointing direction of the electro-optical camera at the time instant of generation of the video image; and correcting the geographic position of each blip in the second reference frame, according to the characteristic features of the camera, in a manner such as to obtain a position in the image.
