Abstract
Using a distance sensor, a set of distances to a target object is measured, a distance in the set being measured at a time. From the set of distances and corresponding times, a trajectory of the target object is predicted. Based on receiving a signal identifying a friendly device, a correlation of the trajectory with a trajectory of the friendly device is determined. Responsive to the trajectory being predicted to intercept a defined volume around the distance sensor and responsive to the correlation being above a threshold degree of correlation, the target object is classified as a threat. Responsive to the trajectory being predicted to intercept a defined volume around the distance sensor and responsive to the correlation being below a threshold degree of correlation, a threat level corresponding to the target object is identified based on the trajectory of the target object and trajectory of the friendly device.
