Abstract
A method, system, and software for using Brillouin precursors to enhance UWB, RF, and Microwave Remote Sensing systems by providing greater penetration depths and or resolution. Embodiments also include methods, software, and systems which provide a method to detect the formation of Brillouin precursor waveforms in any given dispersive media, for any transmitted signal and any frequency range.
Claims39
A method for improving electromagnetic propagation through a dispersive medium, the method comprising:
- predicting and detecting the formation and power decay of one or more Brillouin precursors in the frequency domain for an electromagnetic radiated signal passing through the dispersive medium;
- transmitting and receiving electromagnetic radiation through the dispersive medium;
- and
- making changes to either the transmitted electromagnetic radiation or to signal processing for the received electromagnetic radiation based on the one or more detected Brillouin precursors.
A method for improving the electromagnetic spectrum remote sensing of a target comprising:
- predicting and detecting the formation and power decay of one or more Brillouin precursors for electromagnetic radiation passing through at least one dispersive media;
- determining the dielectric properties of at least one dispersive media between a transmitter and the target;
- transmitting and receiving electromagnetic radiation to and from the target through at least one dispersive medium;
- and
- improving image formation of the target using the results of the predicting, determining, and receiving by adjusting either the transmitted electromagnetic radiation or signal processing for the received electromagnetic radiation.
A method and technique for detecting Brillouin precursors in radio-frequency and microwave frequency domain for improving electromagnetic propagation through a given dispersive medium, the method comprising:
- selecting electromagnetic frequencies for transmission through the given dispersive medium such that Brillouin precursors can be realized at the reception;
- making changes to an amplitude, phase, and shape of the electromagnetic frequencies for realization of the Brillouin precursors;
- modifying system configuration to receive frequency-downshifted electromagnetic signals such that the precursors can be detected;
- and
- performing signal processing on the received electromagnetic signal such that the Brillouin precursors can be realized.
