Exelis为军用机场提供商用货架的精密进近雷达
2016-05-27
【据美国《航宇情报》2016年5月16日报道】美军空中交通管制专家需要用商用现货(COTS)精密进近雷达来取代AN-FPN-63(V) 空中交通管制雷达。他们在美国哈里斯公司全资子公司Exelis Inc那里找到了解决方案。
海军空中作战中心飞机部的官员5月11日宣布授予Exelis一项价值7030万美元的合同,提供42套COTS精密进近雷达系统。这些COTS雷达系统中,美国陆军21套, 美国海军16套, 美国空军5套。
AN/FPN-63(V)精密进近雷达帮助军用飞机在恶劣天气下在机场降落,其在操作员控制台上提供方位、仰角和距离。空管员使用下滑角和中心线偏差等信息引导飞行员进行精密仪表着陆。
AN/FPN-63(V)精密进近雷达自1978年以来一直被美国海军使用,系统即将结束其使用寿命,海军官员说。这个旧系统也变得难以维护。
Exelis将提供一种COTS精密进近雷达,可执行雷达进近和仪表着陆系统(ILS)功能,也可以取代军用机场独立的ILS系统。
Exelis的COTS精密进近着陆雷达系统采用了固态砷化镓发射/接收模块和模块化开放系统架构,能在恶劣天气下工作,有三级天气显示,可以在一分钟之内改变跑道,提供遥控选项,使用COTS处理器,可进行固定、便携式和移动配置,具备内置测试(BIT)监控,使用GPS时间进行同步。
Exelis的COTS精密进近雷达系统有PAR-2000/AN/FPN-68、GCA-2000、AN/MPN-25和PAR-Tactical。其中PAR-2000/AN/FPN-68是帮助飞机在恶劣天气着陆的一种精密进近雷达。
GCA-2000增加了机场监视和二次监视雷达功能。AN/MPN-25是GCA-2000的移动版。PAR-Tactical是基于PAR-2000/AN/FPN-68的移动版精密进近雷达。
军方要求Exelis提供能在五分钟之内重新配置至少8条跑道的精密进近雷达。系统必须能够通过地面控制可以进近到100英尺高度和距离着陆点0.25英里之处。系统的工作温度范围必须为0到122华氏度(MIL-STD-810G),工作高度海拔-100至10000英尺,风速65节。
该合同还要求Exelis为精密进近雷达系统提供不间断电源(UPS),以及培训和辅助安装支持。(中国航空工业发展研究中心 范醴)
 
原文:Exelis to build and install new COTS precision-approach radar systems for military airfields
May 16, 2016
AKEHURST, N.J. 16 May 2016. U.S. military air traffic control experts needed a commercial off-the-shelf (COTS) precision-approach radar to replace the AN-FPN-63(V) radar for air traffic control. They found their solution from Exelis Inc., a wholly owned subsidiary of Harris Corp. in Van Nuys, Calif.
Officials of the Naval Air Warfare Center Aircraft Division in Lakehurst, N.J., announced a $70.3 million contract to Exelis on Wednesday to provide 42 COTS precision-approach radar systems. Of these COTS radar systems, 21 are for the U.S. Army, 16 are for the Navy, and five are for the U.S. Air Force.
The AN/FPN-63(V) precision-approach radar helps military aircraft land at airfields during bad weather. It provides talk-down capabilities to land military and civil aircraft, and works together with airport surveillance radar ground control approach capability for military and civilian aircraft.
The AN/FPN-63(V) provides azimuth, elevation, and range to touchdown on the operator’s console. Air traffic controllers use this information of glide slope and center line deviation to guide the pilot for a precision instrument landing.
The AN/FPN-63(V) precision-approach radar has been in use by the U.S. Navy since about 1978, and the system is nearing the end of its useful life, Navy officials say. This old system also has become difficult to maintain.

Exelis will provide a COTS precision-approach radar that will perform radar approach and instrument landing system (ILS) functions that also can replace stand-alone ILS systems at military airfields.
Exelis designs precision approach landing radar systems with solid-state gallium arsenide transmit/receive modules; modular open-systems architectures; that operate in bad weather; have three-level weather displays; can change of runways in less than a minute; offer remote-control options; use COTS processors; are available in fixed, transportable, and mobile configurations; offer built-in-test (BIT) monitoring; and use GPS time synchronization.
Among the Exelis COTS precision-approach radar systems are the PAR-2000/AN/FPN-68; GCA-2000; AN/MPN-25; and PAR-Tactical. The PAR-2000/AN/FPN-68 is a precision approach radar to help aircraft land in bad weather.
The GCA-2000 adds an airport surveillance and secondary surveillance radar capability. The AN/MPN-25 is a GCA-2000 repackaged into a mobile integrated airport surveillance radar and secondary surveillance radar. The PAR-tactical is a fully mobile precision-approach radar based on the Exelis PAR-2000/AN/FPN-68.

From Exelis military experts want a precision-approach radar that can service at least eight runway approaches reconfigures from one approach to another in less than five minutes. The system must provide for ground-controlled approaches to 100 feet altitude and one-quarter mile from touchdown point.
The system must be able to operate in temperatures from zero to 122 degrees Fahrenheit per MIL-STD-810G, at altitudes from -100 to 10,000 feet, and in 65-knot winds.
The contract also asks Exelis to provide uninterruptible power supplies (UPS) for the precision-approach radar systems, as well as training and ancillary installation support.
