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.

A system for the display of radar returns is provided. The system comprises a radar configured to provide radar data, a processor, and a display configured to present the radar data. The system comprises memory including computer program code configured to, when executed, cause the processor to receive the radar data, wherein an object is represented within the radar data; receive additional data from a data source other than the radar; and determine object characteristic(s) of the object using the radar data and additional data, wherein the object characteristic(s) comprises a position, a velocity, an intensity, or an object classification of one or more objects. The computer program code is also configured to cause the processor to cause presentation of the radar data including a representation of the object and an indication of the corresponding object characteristic(s). A marine electronic device and a non-transitory computer readable medium are also provided.

According to one embodiment, a system includes a radar and a controller. The radar includes at least one first antenna and at least one second antenna. The at least one first antenna transmits a first transmission wave at a first time and transmits a second transmission wave at a second time different from the first time. The at least one second antenna receives reflected waves of the first transmission wave and the second transmission wave.

A method includes obtaining, by a processing device, input data derived from a set of sensors associated with an autonomous vehicle (AV), extracting, by the processing device from the input data, a plurality of sets of features, generating, by the processing device using the plurality of sets of features, a fused bird's-eye view (BEV) grid. The fused BEV grid is generated based on a first BEV grid having a first scale and a second BEV grid having a second scale different from the first scale. The method further includes providing, by the processing device, the fused BEV grid for object detection.
