Small Integrated HFI Sensor for the AVR-2B

Solid State Scientific Corporation (SSSC) is pleased to propose the design of a single-board, integrated Hostile Fire Indication (HFI) system with the nominal size, weight, and power constraints for operation as an adjunct sensor within the AN/AVR-2B(V) Laser Warning Set. Work on Phase I will consist of the preliminary design of a single circuit board that includes an uncooled, Commercial Off-The-Shelf, Short-Wave Infrared (SWIR) focal plane, analog-to-digital circuitry, camera control electronics, digital signal processing electronics, processor and memory electronics for hosting threat warning algorithms, and support and interface electronics. SSSC will design the system using the existing Multi-Function Threat Detector (MFTD) system as a baseline, with the integration of the MFTD camera board, pre-processing board, and processing board onto a single board representing the most important innovation. The design and development of this new, fully integrated multispectral sensor represents a unique opportunity in spectral sensing and imaging. The resulting small, integrated HFI sensor for the AVR-2B system is expected to operate within the existing AN/AVR-2B system using a four-window adapted front plate: one window for the HFI sensor and the other three for laser warning functions. The HFI sensor will operate with small size, weight, and power characteristics with minimal impact on the existing AVR-2B. As a spectral sensor, the HFI system will incorporate a 4-channel optical design for spectral imaging that classifies hostile fire sources by type with high probability of detection and low false alarm rates. Threat warning coverage will be comparable to the field of view of the AVR-2B, with angular resolution in both azimuth and elevation to approximately 1 degrees . This sensor will offer true HFI capability to the helicopter air crew.
