Abstract
An electronically controlled frequency agile impulse source utilizing pulse sharpening techniques to increase its versatility in radiating impulse energy at a variety of center frequencies and bandwidths in the megahertz to the gigahertz range. Such pulse sharpening provides for a radiator having a wider range of applications.
Claims1
An electronically controlled, frequency agile impulse radiator, comprising;
- a semiconductor substrate having at least two opposing surfaces each having a metalized electrode positioned such that electrostatic energy can be stored thereon;
- a power supply means for applying an electric field in a predetermined direction across said electrodes such that said power is stored on said metalized electrodes;
- and
- an optic means for triggering the discharge of said stored energy and abruptly terminating said discharge after a predetermined interval of time, said optic means comprising a laser light source, a beam splitter, and an electronically controlled rotatable mirror, said laser source directing light into said beam splitter such that a first beam is directed into a first fiber optic cable coupled to said top surface electrode, and a second beam is directed to said rotatable mirror electronically positioned such that it directs said second beam into a second fiber optic cable coupled to said bottom surface of said substrate, said second fiber being part of a fiber bundle having a predetermined amount of fibers therein, each fiber in said fiber bundle having different lengths by some predetermined amount greater than said first fiber.
