Methods and systems fort operating one or more light sources to project adversarial patterns generated to disorient a machine learning based detection system, comprising generating one or more adversarial patterns configured to disorient the machine learning based detection system and operating one or more light sources configured to project one or more of the adversarial pattern(s) in association with the targeted object in order to disorient the machine learning based detection system.

A system for providing integrated detection and countermeasures against unmanned aerial vehicles include a detecting element, a location determining element and an interdiction element. The detecting element detects an unmanned aerial vehicle in flight in the region of, or approaching, a property, place, event or very important person. The location determining element determines the exact location of the unmanned aerial vehicle. The interdiction element can either direct the unmanned aerial vehicle away from the property, place, event or very important person in a non-destructive manner, or can cause disable the unmanned aerial vehicle in a destructive manner.

A wave construction method is described that can be used to generate a new and different wave front, which is not parallel to the natural expanding wave front from the emitted signal generated from the source array. Restated, a wave construction method is described that can be used to generate a new and different wave front which is not perpendicular to the direction from the source array to the center of the wave front. This method can also be used to shape a wave in the far field or near field, by changing the locations of the computed points, and generating a linear or non-linear shaped wave (front). This disclosure allows for the controlling, rotating, or shaping radio frequency or acoustic waves in free space or in a fluid.
