PrivaTran proposes to develop a semi-active laser (SAL) receiver read-out integrated circuit (ROIC) with interface to government furnished equipment (GFE) sensor arrays for advanced dual-band SAL receiver systems. Large-area focal plane array (FPA) technology and the PrivaTran ROIC provide high timing accuracy, use of both eye-hazardous and eye-safe lasers, precision guidance, improved weapons delivery accuracy, higher resistance to false targets, enhanced jammer discrimination, and increased overall weapon systems effectiveness while maintaining the same active area as conventional quad-cell systems in a low cost, strap down sensor design. The ROIC provides high-bandwidth sample-and-hold to capture pulse-shape data with enhanced resolution and high signal-to-noise ratio (SNR). The advanced sampling circuit allows pulses to be captured while simultaneously reading the data buffer, resulting in no sampling dead time. These features allow relative range imaging for improved discrimination of false targets such as fog, smoke and other reflections that can cause targeting errors in urban battle field conditions, leading to improved targeting, better friend-versus-foe identification, designator flexibility, and superior jammer resistance.
