Minimization of In-Band Interferers on Airborne Anti-Submarine System Performance

OBJECTIVE: Develop signal processing techniques to isolate and minimize in-band interferences that obscure or degrade the performance of passive or active Anti-Submarine Warfare (ASW) systems.

Awarded to: RDA, Inc.

Contract #: N68335-21-C-0009

Topic #: N182-116

Phase: II

Scheduled Completion Dates:

Base: 1/12/2022
Option: 7/15/2023

Metrics:

  • Pd, Pfa
  • CPU Load
  • Memory Footprint
  • Interference Rejection

Technology Development:

Develop technologies to mitigate the adverse effects of acoustic interference on Anti-Submarine Warfare (ASW) systems.

  • Identify, Quantify, Characterize, Correlate interfering sources
  • Adaptive Algorithms, Metrics, Prototypes
  • Known vs Unknown interferers
  • Field interferer rejection

Phase II Team and Key Personnel:

Prime Contractor: RDA, Inc

  • PI: Jon Dionne
  • IQCC Algorithms, LCAP development

Subcontractor: L3 Harris Adaptive Methods

  • I: Travis Cuprak
  • Adaptive Algorithms

Warfighting Capability:

  • Sensor-agnostic, low system impact capability to significantly reduce or mitigate high-energy acoustic interferers for both passive and active ASW sensors and missions.
  • No impact or change to sonobuoy hardware or software, nor in the RF uplink. All signal processing resides onboard the aircraft.
  • The primary beneficiary of the SBIR technology includes the MAC and MAC-E family of sonobuoys and future sonobuoys, such as the Extended Range DIFAR.
