DRDO Athermal Laser Target Designator

Laser target designators are true force multipliers in modern-day warfare as they enable precision strikes against military targets using laser guided bombs, artillery shells and missiles. The diode pumped Athermal Laser Target Designator (ALTD) is an state-of-the-art military laser equipment that has several distinct advantages over the earlier designators.

Firstly, the athermal design of this designator allows it to operate efficiently over a wide range of ambient temperatures unlike earlier designators that required precise temperature control of the laser diodes using thermo-electric cooler modules for maintaining their performance. This feature of the ALTD has improved the efficiency and reduced the power consumption by almost 40 per cent, thus reducing the size and weight of the battery required. As no active temperature control is required for ALTD, it has negligible start-up time, thereby saving precious time in the battlefield. In comparison, the earlier designators required up to two minutes to be ready for use.

The advanced single channel optics combines the functions of day sight and laser trans-receiver with a common aperture, resulting in a compact, rugged and lightweight design. The designator produces laser pulses with a nominal repetition rate of 20 Hz.

Salient Features

Compact and light-weight.

Built-in Range Finder.

Low power consumption.

Instant start capability.

Built-in DMC and GPS.

Operation with rechargeable Li-ion batteries.

Picatinny rail for mounting SWIRcamera or Thermal Imager.



Design and development of ALTD has led to self-reliance in the field of indigenous development of Laser Target Designators. The ALTD enables ranging and terminal guidance.

Indigenous production of the equipment will result in considerable savings in foreign exchange and help replace unserviceable imported equipments. These systems have the potential to be exported to countries having similar requirements.

Strategic Airborne RADOME based on Frequency Selective by NIT, TRICHY
FSS based on SIW has investigated for airborne radome application. The advantages of FSSs based on SIW (sharp roll-off, flat pass-band, highly stable, high Q-factor, high-power handling and easy to fabricate)
+
now have been considered to design a novel MuItilayer airborne radome to Improve the electrical as well as d physical performance of radome fr challenging facets of modern radar sys.
The EM performance of d proposed element made them a suitable candidate fr radome application.
++The proposed FSS based on SIW will act as a virtually thick screen n possess the adv of a conventional rectangular waveguide, the FSS based on SIW consisted of double-layer FSS n connected wth vias. This helps in equal distribution of heat n reduces

artillery import banned.

 

[IndianHawk]

artillery import banned.

Now ban atgm and tanks too. Also ban all light helicopter imports.

 

[Maniac@666]

artillery import banned.

Let's wait and watch,Don't get your hopes high,imports are banned but they will find loophole.that is they'll will be made in india under make in India category and procured through local vendor. likely Athos will be procured manufactured by Bharat Forge.ive read somewhere that it's even less expensive than 45 cal dhanush.price also matters in our case.same will be the case with MGS(Nexter Caesar through L&T or Denel T5-52 through Tata) though we have our own MGS in development by OFB and more SPH Vajra will bought through L&T(we don't have anything in development other than a prototype of Bhim SPH developed by OFB in collaboration with Denel)otherwise they should've specified Indian make only and whether it's towed arty,MGS or SPH.
