A sniper crouches near an open window and zooms in on his target, who sits a half-mile away. He peers through a scope and holds his breath, preparing to squeeze the trigger. But it’s windy outside, and he can't afford a miss. What to do?
一個狙擊手在半哩遠蹲近開放窗戶和放大他的目標物，他透過一望遠鏡窺看並制住他的呼吸，準備扣動扳機。但外面風大和他負担不起錯失。怎麼辦？
A new DARPA-funded electro-optical system will calculate the ballistics for him, telling him where to aim and ensuring a perfect shot, no matter the weather conditions.
一部由DARPA資助的新光電系統將為他計算出彈道，告訴他放目標在哪裡和確保完美的一擊，不管天氣狀況若何。
Lockheed Martin won a $6.9 million contract this week for the second phase of DARPA’s One-Shot system, which will provide direct observations of a target, measure every variable that influences a bullet’s flight, and calculate the aim offset in a sniper’s rifle scope.
洛克希德馬丁公司這星期贏得一紙690萬美元的合約，為第二階段 的DARPA的一招了系統，它將提供直接的目標觀測，量度每一項影響子彈飛行的變數，並計算出在狙擊手步槍射程的目標偏移。
During the project’s first phase, which started in 2007, Lockheed developed a down-range system that measured average crosswind; range to target; spotter scope position; air temperature, pressure, and humidity; and more, according to Military Aerospace. Using all those variables, it calculated the ballistics for a .308 bullet at ranges as far as 3,600 feet.
While that’s impressive, the system was too heavy and unwieldy, and it couldn’t be used with standard rifle scopes. The phase two design will be more compact and able to operate in real time and over longer distances.
It will measure atmospheric conditions, account for the weapon’s maximum effective range and include GPS coordinates. It’s also supposed to communicate with the rifle scope, informing the gun itself of the aim point offset and expected crosswind.
Lockheed is supposed to deliver 15 field-testable prototypes by next October.
