Abstract
An electromagnetic modulation device may include a receiver configured to receive electromagnetic signals, a digital-to-analog converter configured to continuously generate a modulation signal, a mixer coupled to the receiver and the digital-to-analog converter and configured to encode the electromagnetic signals received by the receiver with the modulation signal generated by the digital-to-analog converter upon receipt of the electromagnetic signals by the receiver, and a transmitter coupled to the mixer and configured to transmit the encoded electromagnetic signals generated by the mixer.
Claims32
An electromagnetic modulation device comprising:
- a receiver configured to receive electromagnetic signals;
- a digital-to-analog converter configured to continuously generate a modulation signal configured to interfere with the received electromagnetic signals;
- a mixer coupled to the receiver and the digital-to-analog converter and configured to encode the electromagnetic signals received by the receiver with the modulation signal generated by the digital-to-analog converter upon receipt of the electromagnetic signals by the receiver;
- and
- a transmitter coupled to the mixer and configured to transmit the encoded electromagnetic signals generated by the mixer,
- wherein the encoded electromagnetic signals are configured to prevent detection of a location of the electromagnetic modulation device.
An electromagnetic modulation method using an electromagnetic modulation device, the method comprising:
- receiving electromagnetic signals using a receiver;
- continuously generating, using a digital-to-analog converter, a modulation signal configured to interfere with the received electromagnetic signals;
- encoding the electromagnetic signals received by the receiver with the modulation signal generated by the digital-to-analog converter upon receipt of the electromagnetic signals by the receiver using a mixer;
- and
- transmitting the encoded electromagnetic signals generated by the mixer,
- wherein the encoded electromagnetic signals are configured to prevent detection of a location of the electromagnetic modulation device.
An electromagnetic modulation system comprising:
- a source device configured to emit electromagnetic signals;
- an electromagnetic modulation device comprising:
- a receiver configured to receive electromagnetic signals from the source device;
- a digital-to-analog converter configured to continuously generate a modulation signal configured to interfere with the received electromagnetic signals;
- a mixer coupled to the receiver and the digital-to-analog converter and configured to encode the electromagnetic signals received by the receiver with the modulation signal generated by the digital-to-analog converter upon receipt of the electromagnetic signals by the receiver;
- and
- a transmitter coupled to the mixer and configured to transmit the encoded electromagnetic signals generated by the mixer,
- wherein the encoded electromagnetic signals are configured to prevent detection of a location of the electromagnetic modulation device.
