Abstract
Cross wind estimation is the largest component in the error budget for long range sniper applications. The Army currently utilizes either point anemometer measurements or visual cues to estimate the cross winds. Aim-point accuracy would be greatly enhanced by precise range-resolved cross wind measurements. CTI proposes a novel compact eyesafe laser cross wind sensor to meet the Army's measurement requirements. The proposed sensor incorporates a scannerless air-cooled transceiver technology which supports a light weight portable packaging concept with no moving parts. In support of near field (less than 59 m) cross wind measurements, the proposed sensor technology incorporates a novel concept for minimizing "transmitter feed-through." Preliminary performance modeling suggests that a quarter Watt sensor will be capable of making high speed, approximately 0.5 Hz, range-resolved cross wind velocity estimates with a precision of less than 1 m/s and a maximum measurement range in excess of 1.5 km. In Phase I CTI will validate the design with computer simulations and an analysis of data collected under a companion CTI R&D effort. Phase I will culminate into a preliminary sensor design, which will be refined, developed, field tested, and evaluated in Phase II. The proposed program will result in the preliminary design of a compact, light-weight, scannerless, air-cooled transceiver for medium range cross wind velocity measurements. This technology will have application in many military as well as commercial settings. Potential commercial applications include, general aviation wind shear detection, airport wind surveillance, environmental monitoring, and in sporting markets like sailing, riflery, etc.
