DARE has established HALT/HASS Test Facility in the year 2011, this facility comprises of a Chamber, Air compressor and LN2 storage tank and is used to conduct accelerated temperature and vibration tests on modules and subunits of systems under development. HALT is used at the design stage of a project to quickly expose the weak points of a design so that the product can be re-designed to remove these weak points, thereby expanding the margins of the design. HASS is used at the manufacturing stage of a project to quickly expose any manufacturing flaws that a particular sample may have. The two principle stresses used during HALT and HASS are rapid temperature transitions (-100º C to +190º C) and 6 degrees of freedom (DOF) random vibration max 60grms.

A fully shielded Indoor Far-field and Hybrid (Single & Multi probe) planar near field Antenna Test Facility to characterize EW antennas has been established in the year 2009. The Antenna Test Facility is first of its kind in India, designed to cover 1 – 40 GHz frequency range for pattern characterization and with a unique capability to measure direction finding accuracy also. The Antenna Chamber size is 18.4 x 10.4 x 9.5m. The Far-Field range is 12 Meter between Tx. & Rx. Antenna with 1.8 meter Quite Zone for accurate characterization of all EW Antennas utilised for RWR, ECM and Direction Finding (DF) applications.

The chamber sensitivity in terms of dynamic range is 60dB min at 18GHz and 40dB min at 40GHz. The chamber has a measurement capability of upto 6 channels. The chamber is capable of characterizing antennas for radiation patterns, gain, axial ratio, polarization, amplitude and phase, null depth, cross polarisation, beam peak, beam width and directivity. The chamber is also used to test the integrated EW system for DF accuracy and Sensitivity. The chamber is completely tested and fully operational.

Range On Wheels 

DARE has developed a Range On Wheels (ROW) facility for evaluating installed specifications of airborne EW systems and for fine tuning ECM techniques. This mobile range consists of a representative

  • Threat Radar,
  • Reference Radar,
  • Slaved Rx/Tx Pedestal System,
  • Data Acquisition Station,
  • Mission Control Station and
  • Generator Vehicle

Data Acquisition Station

Data Acquisition Station, built on a 40 feet trailer, has four independent cabins and a service bay which houses support facilities. The vehicle is fully air-conditioned and it houses an uninterrupted power supply.

Data Acquisition Station provides laboratory environment and houses data acquisition systems, data analysis facilities, real time telemetry, communication, video recording and displays, central timing and a differential GPS base station. The data acquisition systems are PC based and collect information on RS-422 buses. All the PCs are networked for off-line flight data analysis. All the equipment are mounted on 19" consoles with suitable shock mounts.

Mission Control Station

This is a Mission Control Vehicle, where all the activities of flight trials can be monitored and directed. It has a unique configurable display system, using which effective presentations can be made. This vehicles is fully air-conditioned and has UPS and Communication systems.

Slaved Rx/Tx Pedestal System

Slaved Rx/Tx Pedestal System comprising of a servo pedestal, a transmitter antenna, transmitter system, a receive antenna and receiver system. The servo pedestal is slaved to one of the tracking radars. This station will facilitate raDIATion of programmed threat signals towards the EW aircraft under evaluation and also in the measurement of RF power from the on-board ECM systems.

Generator Vehicle

This vehicle houses a 100 KVA, 3 phase generator system and the power is routed to the other vehicles through a power distribution system.

Laboratory Cooling System & Ground Support Equipment

In order to handle high thermal loads generated by high power electronics, several compact cooling systems ranging from forced air cooling to closed loop liquid cooling have been developed and flight-proven.

Automatic Test Equipment (ATE)

The EW suites developed in DARE have RWR, internal jammer and podded jammer. ATE is designed to test all line replaceable units (LRUs) and associated PCBs. It consists of GPIB-based test instruments, ISA bus-based PC add-on measurement cards and custom interface units. Desktop computer serves as the ATE controller. The controller communicates with test instruments via GPIB interface bus and with LRUs via RS-232 and RS-422 serial lines.

The test software is windows-based with excellent graphical user interface. The software is enabled, for conducting the functional tests on LRUs and PCBs, through password protection and provides following additional facilities:

  • Runs self-test on all instruments, adapter boxes and PC add-on cards
  • Calibrates RF paths and video paths between LRU and the tester
  • Dynamically displays test reports in tabular or graphical form
  • Stores test reports
  • Provides facility to take hard copies of the user-selected reports
  • Provides zoom facility to view selected segments of graph
  • Creates history of the user's activities and events
  • Provides extensive help at each level

Addition of new tests or replacement of obsolete test equipments can be done with minimum changes in the software core. The instrument driver interfaces and functional tests are designed as DLLs (Dynamic Link Libraries) to provide maximum flexibility in tester maintenance. The ATE is operational at user's site for performance evaluation.

Dynamic Avionics Integration Rig(DAIR)

DAIR for LCA is used to carry out extensive testing of all the functions of the aircraft on the Rig. This facilitated in successful of LCA and the Rig is now getting updated for LCA. Termed as Flight-On-Ground, this facility is now developed for the fighter aircraft upgrade programme for testing all the avionics interfaces and avionics integration. Successful flight testing of fighter aircraft with upgraded avionics was possible due to rigorous testing carried out with the help of this facility.
