Research Topics


A multifunction look-forward, look-down coherent Doppler ladar system has been identified for use onboard military and commercial aircraft to monitor the wind shear environment ahead and to allow target identification by precision measurement of target range, velocity, and vibration spectra. The proposed Phase II effort is a first step toward the development of such a ladar. In its ultimate form, the instrument will be an airborne scanning ladar with processing and display system that is capable of: imaging wind fields below the flight path created by wakes of multiple leading aircraft flying in formation over a drop zone; vertical wind profiling and hazardous wind shear detection; detection and tracking of hazardous wake vortex encounters along approach corridors and during formation flying, refueling or combat at moderate altitudes; clear-air turbulence (CAT) mitigation at cruise altitudes; hard target discrimination and identification; and terrain profiling.The proposed Phase II effort develops key subsystem components that, together with other companion efforts ongoing at CTI, drive toward a truly multifunction airborne sensor with strong commercial viability. Critical proof of concept demonstrations are to be conducted in Phase II and will lead to flight-testing and eventual commercial product sales in Phase III.
