Dr. John Burke joined DARPA as a Program Manager in the Microsystems Technology Office (MTO) in August 2017. His research interests include the development of high-stability, low-noise sensors and frequency synthesis to enable new positioning, navigation, and timing (PNT) and remote detection capabilities. He is particularly interested in the integration of modern atomic physics techniques (e.g. laser cooling and trapping) with photonic circuits and atom chips to reduce the complexity, cost, and size of these techniques while increasing their robustness and reliability for use outside of a laboratory environment.

In this episode DARPA’s podcast, MTO program manager Dan Green discusses the Agency’s work to develop semiconductor materials, among them gallium arsenide and now gallium nitride, that open pathways to both military and civilian technology in categories spanning from electronic warfare to radar to communications.

Most people are familiar with the concept of RADAR. Radio frequency (RF) waves travel through the atmosphere, reflect off of a target, and return to the RADAR system to be processed. The amount of time it takes to return correlates to the object’s distance. In recent decades, this technology has been revolutionized by electronically scanned (phased) arrays (ESAs), which transmit the RF waves in a particular direction without mechanical movement. Each emitter varies its phase and amplitude to form a RADAR beam in a particular direction through constructive and destructive interference with other emitters.

The increased density of electronic components and subsystems in military electronic systems exacerbates the thermal management challenges facing engineers. The military platforms that host these systems often cannot physically accommodate the large cooling systems needed for thermal management, meaning that heat can be a limiting factor for performance of electronics and embedded computers.

The U.S. Military relies on the space-based Global Positioning System (GPS) to aid air, land and sea navigation. Like the GPS units in many automobiles today, a simple receiver and some processing power is all that is needed for accurate navigation. But, what if the GPS satellites suddenly became unavailable due to malfunction, enemy action or simple interference, such as driving into a tunnel? Unavailability of GPS would be inconvenient for drivers on the road, but could be disastrous for military missions. DARPA is working to protect against such a scenario, and an emerging solution is much smaller than the navigation instruments in today’s defense systems.
