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

LEGACY TPQ-36/37 RADARS CAPABILITIES

TPQ-36/37 WITH ROCS CAPABILITIES

FMS versions of the  TPQ-36 and TPQ-37 around the world, use  analogue mapping with mechanical DRUM and topographic paper maps. The 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.
The 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. 

 

TPQ-36/37 radar with ROCS is faster and more accurate. Using Digital Terrain Elevation Data Level II (DTED level II)  with powerful processors make these radars locate, display and communicate 10 Weapons (or more) per minute. 


Running the radar system in 'Automatic mode' 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.

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. The upgraded OCG, includes two Workstations with two 19" BARCO LCD displays. The ROCS system enables additional Laptop Workstations running by Operators or technicians inside or outside the radar shelter.  The User may add additional workstations on Laptops via the system LAN.  
The left side Workstation is called ‘
Weapon Location Display’. It is used for radar operation, target acquisition, and weapon location.
The right side Workstation is called ‘
Fire Mission Display’. It is used by radar Officer for management, Fire mission, and communication purposes.
The 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. TPQ-36/37 Radar with ROCS tracks and stores up to 500 hostile targets.  
Legacy TPQ-36/37 Radar Shelter Operators might be killed by a direct  enemy fire on the radar 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.
In Friendly mode, the legacy TPQ-36/37 radar has only 3 friendly buffers.  TPQ-36/37 Radar with ROCS can store 25  Batteries and 100 friendly rounds.  

FRIENDLY REGISTRATION SCREEN

High skilled operators are needed for the operation of the legacy TPQ-36/37 Radars. They must memorize and use Function Codes, and enter the system (manually) lot of parameters. Threfore the Weapon detection rate depends on the Operator's proficiency. TPQ-36/37 Radar with ROCS automates the operation and reduce the proficency requirements on operators  
Legacy  TPQ-36/37 Radar operator can define up to 6 Artillery zones  TPQ-36/37 Radar  with ROCS provides up to 50 Artillery Zones with priorities.  
The radar connectivity to Command & Control is via TACFIRE Fire Net interface. 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.  
Initialization and program Loading of the legacy TPQ-36/37 Radars is slow due to programs loading time using Raymond Cassettes  Radar with ROCS has Automatic Initialization and program loading.   

Radar Initialization Screen

Existing Shelter 28DC power supply has limited power 
(17 Amps). It can support only 2 analog radios. 
The system does not support communication when the Generator is down. 
TPQ-36/37 Radar Shelter with ROCS includes a 50 Amps Power Supply/UPS and Battery Bank Charger.  The system  supports full communication with C2 when the Generator is down. 
In the Legacy systems on paper from radar printer are available for debriefing.  TPQ-36/37 Radar with 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.   
Training with Field Exercise Mode (FEM) is for one Operator.  ROCS makes possible to train a group of Users in a remote classroom via LAN, (running FEM).
A Classroom Simulator for Artillery school is also available. 

The radar  requires UTM maps on WGS-84 Datum.

TPQ-36/37 Radar with ROCS can be programmed to use maps based on different Datum and output   Weapon locations and impacts in any coordinate system.  
Legacy TPQ-36  Shelter  is not interchangeable with TPQ-37 Shelter. The Shelter of TPQ-36/37 with ROCS is fully interchangeable with the TPQ-37 Shelter. The ROCS can load radar programs of both systems.  
Legacy TPQ-36/37 includes  low reliability assemblies. TPQ-36/37 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) solves this shortcoming.

 

ROCS-PSU is an integral part of ROCS system. It supplies 28VDC 1250Watt to radios and  the ROCS equipmentf.

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.
