Digital Radar Tech to Enable Distributed Sensing.
Author | Tegler, Jan |
Position | Innovation Nation |
SEVERNA PARK, Maryland--A new digital radar architecture in development at Sandia National Laboratories is intended to shift the paradigm for military sensing.
The new technology replaces analog signal processing hardware with digitally based signal processing firmware and software that can be downloaded for different missions to a small toolbox-sized piece of equipment that meshes with existing and future sensors.
It takes radars "from a few exquisite sensors to a distributed [electronic warfare], distributed communications, distributed intelligence paradigm," said Jacques Loui, technical lead for Sandia's multi-mission radar frequency architecture.
The architecture allows a single sensor to perform multiple tasks "like a Swiss Army knife," diminishing space, weight and power requirements, Loui said. Hypothetically, the sensors could be placed in a variety of unmanned aircraft, manned aircraft and even weapons to form a distributed sensing network of platforms that can communicate and collaborate.
The digital architecture's flexibility could allow a sensor to tackle an EW mission on one sortie, then perform intelligence, surveillance and reconnaissance on the next, he said.
It has the potential to help realize the military's concept of replacing expensive, mission-dedicated aircraft like the EA-18G Growler with large numbers of inexpensive drones and smart weapons, he said.
The rapidly upgradeable, reconfigurable architecture employs advanced electronic components developed...
