PQ-36/37 radars, fielded in 1981, are excellent battlefield proven  Radar Systems. Radar Operational Control System (ROCS) improves the performance of these outstanding radars at minimum cost.

LEGACY TPQ-36/37 RADARS CAPABILITIES

  • FMS versions of the  TPQ-36 and TPQ-37, have  analogue mapping with mechanical DRUM and topographic paper maps. Users of these WLR systems do not use 'Automatic Height Correction (AHC) based on Digital Terrain Map data. Therefore, they must perform Manual Height Correction in order to accurately locate enemy Mortars and Artillery.
    Manual Height Correction is time consuming process that limits the number of detected Weapons to  2-3 targets  per minute. Moreover, the  Height Correction function does not exploit the full acquisition and detection capability of the radar because the User must treat each target separately before radioing its coordinates (via voice or via TACFIRE). This manual process reduces the number of processed targets transferred to remote Users.
     

  • The Legacy TPQ-36 or TPQ-37 radar is built for one Operator. During Combat it is necessary to have more operators and technicians in the radar Shelter. In fact, the new US ARMY shelters have two workstations with a option to operate the radar from remote.

 

TPQ-36/37 WITH ROCS CAPABILITIES

  • ROCS detects weapon faster and more accurate. With its powerful processors, it locates, display and communicate 10 Weapons (or more) per minute. 
    Running the radar system in 'Automatic mode' using Digital Terrain Elevation Data  (DTED level II), provides the operator with a fully automated height correction, and a seamless pass of targets.  This mode can be used during heavy artillery activity to collect large number of hostile weapons, and process and communicate as many targets as quickly as possible.  Whenever a new target arrives, it is automatically height corrected, processed and sent to remote users without operator interaction.
     

     

  • ROCS Shelter, includes two Workstations with two 19" BARCO displays. Additional Laptop based Workstations can join the network inside or outside the radar shelter.  The left  Workstation is called ‘Weapon Location Display’. It is used for radar operation, target acquisition, and weapon location. The right Workstation is called ‘Fire Mission Display’. It is used by radar Officer for management, Fire mission, and communication purposes. Using two Workstations allow radar Operators to share the workload and increase the throughput of target detection and data communication to headquarters and batteries.

    ROCS Main SCREEN

  • TPQ-36/37 Radar stores in its permanent buffer only 99 targets.

  • Legacy TPQ-36/37 Radar Shelter Operators might be killed by a direct  enemy fire on the radar

     

  • In Friendly mode, the legacy TPQ-36/37 radar has only 3 friendly buffers. 

 

  • ROCS tracks and stores up to 500 hostile targets.  

  • For protection, Operators may operate the TPQ-36/37 Radar with ROCS from remote Laptops using LAN or Wi-Fi. B Scope picture is available on all Workstations as well as  remote Laptops.

  • Radar with ROCS stores 25  Batteries and 100 friendly rounds.  

FRIENDLY REGISTRATION SCREEN

  • Require Highly skilled operators for the  legacy TPQ-36/37 Radars. They must memorize and use Function Codes, and enter the system (manually) lot of parameters. Therefore the Weapon detection rate depends on the Operator's proficiency.
  • Legacy  TPQ-36/37 Radar operator can define up to 6 Artillery zones 
  • The radar connectivity to Command & Control is via TACFIRE Fire Net interface.
     

  • Initialization and program Loading of the legacy TPQ-36/37 Radars is slow due to programs loading time using Raymond Cassettes  
 
  • TPQ-36/37 Radar with ROCS automates the operation and reduce the proficiency requirements on operators  

     
  • Radar  with ROCS provides up to 50 Artillery Zones with priorities.  
  • TPQ-36/37 Radar Shelter with ROCS is an open architecture. Implementation of any desired protocol to communicate digital data  to other radar systems, C2 and Batteries, is possible.  

  • Radar with ROCS has Automatic Initialization and program loading.   

 

Radar Initialization Screen 

  • Legacy Shelter  power supply has limited 28DCpower (17 Amps). This power supports 2 analog radios. The system does not support communication when the Generator is down. 
     
  • In the Legacy systems on paper from radar printer are available for debriefing. 
     
  • Training with Field Exercise Mode (FEM) is for one Operator. 

     
  • The radar  requires UTM maps on WGS-84 Datum.
     

  • Legacy TPQ-36  Shelter  is not interchangeable with TPQ-37 Shelter.
     

  • Legacy TPQ-36/37 includes  low reliability assemblies.
 
  • ROCS Shelter includes a 50 Amps Power Supply/UPS and Battery Charger. ROCS  supports full communication with C2 when the Generator is down. 
     

  • ROCS collects and records   comprehensive  digital data for debriefing (hostile Targets, Friendly targets, C2 messages, Printer log, B Scope recorded video etc'., for later debriefing.
     

  • Users of the Radar with ROCS can be trained from a remote classroom via LAN, (running FEM). A Classroom Simulator for Artillery school is also available. 
     

  • ROCS can be programmed to use maps based on different Datum and output Weapon locations and impacts in any coordinate system.  
     

  • ROCS TPQ-36 Shelter is fully interchangeable with ROCS TPQ-37 Shelter. The ROCS can load radar programs of both systems.  
     

  • Radar with ROCS does not include Raymond Cassette and DRUM. The system may work without existing B-Scope and Printer  assemblies.

ROCS-PSU Military UPS

 

Existing 24VDC Shelter Power Supply (rated 400Watt). is designed to support two analog radios. Unfortunately, new digital radios requires more power. ROCS Power Supply/UPS (ROCS-PSU) is the solution of this shortcoming.  ROCS-PSU is an integral part of ROCS system. It supplies 28VDC 1250Watt to radios and  the ROCS equipment. The unit has three functions:

  • Power Supply - For the Shelter radios and ROCS equipment..

  • Battery Charger - The ROCS-PSU charges 24VDC External  Battery Bank. Battery charging is done in parallel to  supplying DC to radio sets and  the ROCS itself.

  • UPS Unit - for emergency and for  ‘On the Move’ capability.

 

 

The ROCS-PSU gets its power from two sources;

  • DC power from External Battery Bank installed on the truck.

  • 115VAC 3Ø 400Hz Generator via the Shelter’s PDU.

The Battery bank is GFE batteries of 4 x 12VDC, 120hA. This provides energy of 240hA. During normal operation the ROCS-PSU is powered from the radar generator. When the generator is Off the ROCS-PSU gets its power from the battery bank. The ROCS-PSU (UPS) power is sufficient to keep live three radios, and the ROCS during ‘On The Move’ or power trip periods.

Note: The ROCS system draws approximately 6Amp from the ROCS-PSU supply.
