Abstract
Not Available The most cost-effective, scalable format for the development of high power ladar and directed energy systems is to combine medium power laser modules into a coherently phased array. To this end, CTI proposes to develop a coherent synthetic aperture, synthetic wavelength ladar system based upon modular, tunable fiber lasers/amps. It is suggested that high spatial and spectral coherence fiber lasers/amps are the enabling technology for practical arrays. Achieving commensurate power-aperture products with bulk media power oscillators and/or optical amplifiers would be challenging and costly. Moreover, phased arrays have proven to be challenging for semiconductor lasers. Phase I focuses on designing a sensor system and a matched optical phase control servo. The proposed system has similarities to radar, and provides a path to orbital-class detection ranges. Aperture synthesis and the inherent phased array baseline provide superior cross-range resolution. Synthetic wavelength interferometry and waveform coherence encoding provide line-of-sight range resolution (for CW operation). Precision phase control enables array focusing, steering, and adaptive optics at high temporal bandwidths without moving parts. Phase I will investigate innovative optical phase controls network and metering trusses. Risk reduction measurements will be performed. Phase II's goal is to build a first-of-kind phased array sensor and utilize CTI's flight-worthy systems experience to ensure a path to airborne hardware.
