AN/SPS-67(V) Radar Set | | | Description
The AN/SPS-67(V) is a search and surveillance radar designed primarily for use on surface vessels. The radar performs the functions of navigation, station keeping, and general surface search functions. The AN/SPS-67(V)3 & 5 variants additionally provide a quick reaction automated target detection and track capability to the MK 34 Gun Weapon System (GWS) in surface engagements, low elevation air engagements, and Naval Gunfire Support aboard the DDG Ship Class.
AN/SPS-67(V)1 was installed in the 1980s on LCC, LHD, LHA, LSD, LPD, CV & CVN ships. The AN/SPS-67(V)3 was installed beginning in the 1990s on DDG 51-102. It was implemented to provide track data to the Gun Weapon System (GWS) via AEGIS C&D. AN/SPS-67(V)5 installations began FY07-Q4 aboard DDG 72-102 (Back fit) and DDG 103-112 (Forward Fit). It is currently planned to be installed aboard DDG 113 and follow-on hulls. The AN/SPS-67(V)5 is a COTS Refresh for AN/SPS-67(V)3 Radar which eliminates all the SEM modules, replaces the Signal Processor Unit with new VME Based COTS processors and maintains/exceeds existing (V)3 requirements and interfaces.
The AN/SPS-67(V)5 has been tested and qualified to Shock MIL-STD-901D, Vibration MIL-STD-167 and EMI certification MIL-STD-461D&E.
The AN/SPS-67(V)5 radar is maintained by an ET NEC 9615; tactical operation and monitoring of the radar’s AEGIS C&D interface is performed by an OS from the ship’s Combat Information Center (CIC) console in the Surface Detector Tracker sub-mode, as a collateral duty. There are no watch station requirements for this system.
AN/SPS-67(V) maintenance training is provided in an instructor-guided classroom format using Computer Aided Instruction (CAI) modules to train and learn equipment operation, testing, fault identification, and system troubleshooting. Part-Task Trainers (PTT) are used to train students in transmitter modulator driver assembly maintenance tasks. Students also use the radar’s Interactive Electronic Technical Manual (IETM) in the classroom.
An Electronic Technician (ET), Navy Enlisted Classification (NEC) ET-9615 performs the organizational-level (O-Level) preventive and corrective maintenance. The maintenance technician is required to troubleshoot, fault isolate, and replace faulted LRU and, in some instances, isolate and repair faults at the piece-part level. The SM&R codes in the system’s provisioning documentation identify the repair level for each maintenance significant item. Troubleshooting and fault isolation of COTS parts is primarily accomplished by system BIT function. BIT identifies and isolates 95% of detected faults to a single LRU in the parts it monitors within the Receiver Processor, and to a maximum of four LRUs within the R/T, PDU, and ACU. BIT measures output power, noise figure, and Voltage Standing Wave Ratio (VSWR) while the radar is operating. BIT does not degrade the radar performance while the radar is operating.
| | | Features
The current AN/SPS-67(V)5 radar is a two-dimensional (azimuth and range) pulsed radar set primarily designed for surface operations with a secondary capability of anti-ship-missile and low flier detection. The radar set operates in the 5450 to 5825 MHz range, using a coaxial magnetron as the transmitter output tube. The transmitter/receiver is capable of operation in a long (1.0 µs), medium (0.25 µs), or short (0.10 µs) pulse mode to enhance radar performance for specific operational or tactical situations. Pulse repetition frequencies (PRF) of 750, 1200, and 2400 pulses/second are used for the long, medium, and short pulse modes, respectively. The antenna can be rotated at two different speeds (15 and 30 RPM) and the system includes an automatic tracker. The system also operates as the backup IFF antenna.
The AN/SPS-67(V)5 radar set includes seven major functional elements: Radar Set Control (RSC), Receiver-Transmitter (RT), Power Distribution Unit, Antenna Control, Antenna Safety Switch, Antenna, and Radar Processor (RP). The radar is used on Flight II and IIA DDGs. All below deck hardware is located in radar room #2, which is in a cipher locked room, with the exception of the RSC which is located in Combat Information Center (CIC) that is also a cipher locked area.
The RP processes 60 MHz Intermediate Frequency (IF) from the RT and provides display video and track/contact data output as directed by the operator via the Command and Decision (C&D) system. The RP provides automatic target detection, centroiding, and tracking of targets. It provides track and contact data to C&D for Gun Weapon System (GWS) use. The RP also features a comprehensive Built In Test (BIT) that allows fault detection and localization down to the Lowest Replaceable Unit (LRU) level. The unit is a bulkhead mounted cabinet containing a control panel, multi-voltage power supply, power conditioning and distribution subassemblies and a VME card rack subassembly.
The Radar Processor Control Panel (RPCP) provides radar and BIT controls using a Thin Client that provides a menu driven windowed display interface. Operator inputs are made using a touch-sensitive overlay on the display screen. The RPCP communicates with the Tracker Processor, Centroid Processor, and RSC via the internal LAN. The RSC provides the operator controls using a windowed Graphical User Interface (GUI) with a touch screen. Radar operating modes are selected using the touch screen and the associated display menus. Radar status is displayed on the RSC.
The AN/SPS-67(V)3 &5 radars are compatible with and meet the interface requirements of the AN/SLA-10, Identification Friend or Foe (IFF) equipment, Radar Display and Distribution System (RADDS), Data Multiplex System (WS-21333), and AEGIS C&D (WS-21343).
The AN/SPS-67(V)5 utilizes a Built In Test (BIT) function which is designed to locate 95% of BIT monitored Receiver-Processor failures to a single maintenance module, and to a maximum of four maintenance modules within the Receiver/Transmitter, Power Distribution Unit and Antenna Control Units. Output power, noise figure, and Voltage Standing Wave Ratio (VSWR) measurements are measured while the radar is operating. The BIT function does not degrade the performance of the radar during normal operation.
| | | Background
In 1983 Northrop Grumman Norden Systems (NGNS) commenced production of the AN/SPS-67 radars, producing a total of one hundred twenty-six (126) AN/SPS-67(V)1 radars and thirty six (36) AN/SPS-67(V)3 radars. In 1997, procurement of the AN/SPS-67(V)3 Radar was split into two solicitations, one for below deck equipment and one for the above deck Antenna Group. Both contracts were competitively awarded and the resulting two procurements included fulfillment of all system requirements through FY 2001. In the split procurement, the below decks equipment contract, for 26 units, was awarded to DRS Electronic Systems while the Antenna Group contract, for 26 units, was awarded to Electro-Mechanical Systems (EMS).
In FY 2003, two follow-on contracts were awarded in support of additional radar system procurements. A Sole-Source contract was awarded to DRS Surveillance Support Systems, Inc. for 12 AN/SPS-67(V), three below deck units and procurement of 26 AN/SPS-67(V)5 COTS Refresh Kits. The Antenna Group contract was re-competed and awarded to EDO Corp. for 17 antenna units.
Program Office is currently in process of awarding a procurement contract for the acquisition of 12 additional below deck systems, 12 above deck antenna groups and one refurbishment/upgrade of an AN/SPS-67(V)3 radar system to support DDG 51 Re-Start program through FY 2020. AN/SPS-67(V)5 is currently installed in DDG 51 Class ships and interfaced with existing shipboard systems. An Engineering Design Agent (DA) contract associated with the continued engineering, maintenance, system enhancements and mitigating obsolescence is currently in place to support AN/SPS-67(V) system life cycle sustainment.
