1. A system comprising:
a radar assembly configured to be mounted to a mobile structure; and
a logic device configured to communicate with the radar assembly, wherein the logic device is configured to:
receive Doppler radar returns corresponding to a detected target from the radar assembly;
determine a radial velocity spectrum associated with the detected target based, at least in part, on the received Doppler radar returns;
determine a probability the detected target comprises a wildlife feeding flock which is a flock in a process of feeding on wildlife, based, at least in part, on the determined radial velocity spectrum and wildlife feeding flock characteristics; and
generate radar image data based, at least in part, on the received radar returns, the determined radial velocity spectrum, and the determined probability the detected target comprises the wildlife feeding flock.
