Techniques are disclosed for systems and methods to provide remote sensing imagery for mobile structures. A remote sensing imagery system includes a radar assembly mounted to a mobile structure and a coupled logic device. The radar assembly includes an imaging system coupled to or within the radar assembly and configured to provide image data associated with the radar assembly. The logic device is configured to receive radar returns corresponding to a detected target from the radar assembly and image data corresponding to the radar returns from the imaging system, and then generate radar image data based on the radar returns and the image data. Subsequent user input and/or the sensor data may be used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

Radar and colocated camera systems and methods

Techniques are disclosed for systems and methods to provide wildlife feeding flock detection using a remote sensing imagery system. A remote sensing imagery system includes a radar assembly mounted to a mobile structure and a coupled logic device. The logic device is configured to receive radar returns corresponding to a detected target, determine a radial velocity spectrum associated with the detected target based, at least in part, on the received radar returns, and determine a probability the detected target includes a feeding flock based, at least in part, on the determined radial velocity spectrum. The logic device may generate radar image data based on the received radar returns, the determined radial velocity spectrum, and/or the probability the detected target includes the feeding flock. Subsequent user input and/or the sensor data may be used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

Techniques are disclosed for systems and methods for video based sensor fusion with respect to mobile structures. A mobile structure may include at least one imaging module and multiple navigational sensors and/or receive navigational data from various sources. A navigational database may be generated that includes data from the imaging module, navigational sensors, and/or other sources. Aspects of the navigational database may then be used to generate an integrated model, forecast weather conditions, warn of dangers, identify hard to spot items, and generally aid in the navigation of the mobile structure.

Techniques are disclosed for systems and methods to provide perimeter ranging for navigation of mobile structures. A navigation control system includes a logic device, a perimeter ranging system, one or more actuators/controllers, and modules to interface with users, sensors, actuators, and/or other elements of a mobile structure. The logic device is configured to receive perimeter sensor data from ultrasonic perimeter ranging sensor assemblies of the perimeter ranging system and generate an obstruction map based on the received perimeter sensor data. The logic device determines a range to and/or a relative velocity of a navigation hazard based on the received perimeter sensor data. The logic device determines navigation control signals based on the range and/or relative velocity of the navigation hazard. Control signals may be displayed to a user and/or used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

A method for providing enhanced sonar images includes ensonifying a target column of water with sonar beams corresponding to pulses of continuous wave (CW) and pulse compression (FM) signals. Received acoustic returns are processed to generate sonar image data corresponding to the CW signals and the FM signals. The CW and FM sonar image data are then displayed contemporaneously such that one sonar image data set overlays another. Techniques are also disclosed to provide situational imagery. A pilot display system includes a user interface, a logic device, and a speed sensor mounted to a mobile structure. The user interface is configured to receive user input and provide user feedback, and the logic device is configured to receive a speed of the mobile structure from the speed sensor, generate corresponding situational image data, and render the situational image data via at least one display of the user interface.

3D sonar systems and methods

Techniques are disclosed for systems and methods to provide a staggered multichannel transducer in a ranging system configured to perform remote sensing. The staggered multichannel transducer may extend in a first direction and one or more transducer elements of the array may offset from the other transducer elements in a second direction perpendicular to the first direction. The staggered arrangement of the transducer elements may improve remote sensing performance to produce accurate remote sensing data and/or imagery. The staggered arrangement also may reduce a number of transducer elements used in the transducer array which reduce the cost and complexity of the transducer array. Further, the staggered arrangement in a linear transducer array also allows for two-dimensional beam forming.
