COMINT Experience

HF and V/UHF (high-frequency and very/ultra-high frequency) tactical communications intelligence (COMINT) solutions are designed, developed, and provided by Southwest Research Institute (SwRI). SwRI provides COMINT and DF (direction-finding) tactical products for a variety of operations, including:

  • Shipboard
  • Submarine

SwRI's solutions incorporate our field-proven technology for both HF and V/UHF applications. Products include both sensors and antennas, which, when paired together, create an end-to-end COMINT/DF system.

DF Antennas

SwRI DF antennas provide world class DF accuracy. The antennas are offered in a variety of form factors to match different concepts of operation, from permanent, ruggedized installations to temporary, rapid setup/tear-down situations. SwRI is able to tailor existing antenna products to unique platform constraints, while maintaining exceptional DF accuracy across a wide frequency range and full 360° azimuth.

Sensor Products

SwRI sensors are largely based on commercial off-the-shelf (COTS) hardware components, which reduces cost and increases reliability, modularity, and flexibility. As such, the sensors can be tailored to meet specific program requirements for size, weight, power, and performance. The sensor products range from miniaturized, lightweight units with focused processing to larger sensors with the full SwRI suite of capabilities.
