Abstract: US Navy relies on directed energy (DE) weapons, such as High-Power Microwave (HPM) sources, to disrupt, damage, or destroy foe electronic equipment at a standoff distance while minimizing collateral damage. Friendly and blue force mission critical electronic systems, such as radar, communications, navigation, sensors, guidance, fire control, etc. are vulnerable to both friendly and enemy DE weapons. US Navy requires test capability to generate arbitrary HPM signals in order to both improve the effectiveness of its DE weapons against specific enemy targets and to reduce the susceptibility of friendly systems to foe DE attacks. We propose to address the Navy requirement for a flexible and efficient HPM test capability by leveraging our prior Navy-funded work and innovative concepts to develop a solid-state High-Power Radio-Frequency (HPRF) source based on a planar and modular Non-linear Transmission Line (NLTL) RF oscillator triggered through a ultra-fast stacked MOSFET high-voltage switch. The wavelet synthesis approach will be utilized to generate essentially arbitrarily shaped waveforms by adjusting relative delays and amplitudes among array elements.
Benefits: Signal generation equipment for current and future counter-IED directed energy and jamming systems requires significant frequency agility, high power, broad operating bandwidths, and a variety of waveforms that can be switched quickly and with high efficiency in response to emerging threats. The proposed pulsed source solution represents a highly versatile technology platform that can incorporated into a variety of joint-service counter-RCIED systems currently deployed in the theater, as well as future systems, to provide improved performance, reduced SWaP, and extended capabilities. The ferrite NLTL-based microwave sources that rely on such pulsed-voltage modules are capable of peak power of 100s of MW in a compact form factor. Thus far, the dimensions, weight, and power requirements have prevented the development of practical HPM systems and their deployment to the warfighter. The research and development program set forth in this proposal has the potential to significantly advance the existing state-of-the-art and bridge the gap between laboratory demonstrations and deployment in the field. We will also market pulsed power sources to OEMs in semiconductor processing, plasma electronics, tool and die hardening, as well as the emerging metal corrosion protection, and high-performance ceramics market segments.
