A high-altitude electromagnetic pulse (HEMP) detection system, comprising:
- a dual-loop antenna, including:
- an antenna substrate having a first side and a second side opposite the first side;
- a first loop antenna located on the first side of the antenna substrate, the first loop antenna having a first polarity;
- and
- a second loop antenna located on the second side of the antenna substrate, the second loop antenna having a second polarity opposite the first polarity.
A method performed by a high-altitude electromagnetic pulse (HEMP) detection system, the method comprising:
- detecting, while operating in a low-power mode, an electromagnetic pulse (EMP) at a dual-loop antenna based on the EMP charging a capacitor with an EMP voltage;
- filtering, while operating in the low-power mode, the EMP voltage from the dual-loop antenna for a plurality of voltage profiles;
- and
- based on the filtered EMP voltage exceeding a threshold voltage, initiating a power wakeup on a microcontroller to initiate operation of the HEMP detection system in an analysis and transmission mode.
A method performed by a high-altitude electromagnetic pulse (HEMP) detection system, the method comprising:
- receiving an electromagnetic pulse (EMP) at a dual-loop antenna based on the EMP charging a capacitor with an EMP voltage;
- filtering the EMP voltage with a plurality of event discrimination filters resulting in a plurality of filtered EMP voltages, each event discrimination filter associated with an EMP event;
- and
- identifying an EMP event type based on a filtered EMP voltage of the plurality of filtered EMP voltages exceeding a filtered EMP threshold.
The method of 18, wherein identifying the direction of the HEMP event includes identifying a location and an elevation of the HEMP event.
