Radar systems and methods detecting and tracking an unmanned aerial system (UAS) are provided. The radar system and methods can include determining whether or not a UAS is included in the plurality of electromagnetic signals received by the radar system based on one or more expected frequencies that one or more UAS devices use to transmit signals to remote controls. The radar systems and method can also involve switching the radar system into a track mode upon detecting a UAS.

Systems and methods for detection and tracking of unmanned aerial systems

A calibration circuit includes a plurality of signal sources each of said signal sources having an output port and providing a signal having a known phase and a signal combiner circuit having a plurality of input ports and an output port with each of said input ports being coupled to a corresponding one of said signal source output ports. The calibration circuit further includes a switch having a common port and at least one branch port, said branch port being coupled to said output port of said signal combiner circuit and an analog to digital converter circuit having an input port coupled to the common port and an output port. The calibration circuit further includes a central processing unit coupled to the output port of said analog to digital converter and a summing circuit having a first input port coupled to said central processing unit, a second input port coupled to the output port of said analog to digital converter circuit and an output port.
