It’s deployment of weapons like this that will demotivate Commanding officer level guys on the other side of the border. This will definitely bring the moral down on the other side of the fence.
This is for bringing down drones at IB, range 4km.

Can it be used to target enemies Temporary Posts?
In the long run if automation is the future than we should decrease manpower on the frontline by putting work load on Robots and automatic systems.

That’s why, When the first pictures came out, I talked about the vehicle managing gradient when moving.

Without odd road capability, how can it be positioned to take out temporary posts in a 4 km range. roads will not always be there.

Acoustic Gunshot Detection System(C-DAC)

Acoustic Gunshot Detection System detects and conveys the location of source using an array of acoustic sensors. These systems can be used by military, law enforcement and security agencies to identify the direction of gun fire, the source and in some case the type of weapon faired.

Main uses and domain

Acoustic Gunshot Detection System (AGDS) is the first indigenized field tested product. Indigenization of the system made it affordable, especially in cases where large numbers are required, as in border areas for 24 x 7 security surveillance. AGDS can be fixed to land, water or air based vehicles of Indian Defence forces. AGDS can also be fixed to high security buildings, strategic installations and insurgent prone areas to give precise warning about possible hostile gun fire. The technology will be of great interest for Indian security agencies namely Indian army, BSF, CRPF, ITBP, State police, NSG, SPG etc.

Features and Technical Specifications

Shot Detection Parameters

Gun detected : Small fire arms like INSAS, AK 47,Sniper etc.

Detection Accuracy in Azimuth angle: ± 5 degree

Detection Accuracy in Elevation angle: ± 5 degree

Preparations are going on to ensure that the deal for procuring for 30 Drones from the US-based General Atomics worth $ 3 billion be inked before the close of this financial year. The three services are expected to get 10+10+10 the MQ-9 Reaper or Predator-B High Altitude Long Endurance (HALE) drones, which have already been approved by the US President Donald Trump’s administration. The US administration’s approval includes the sale of armed drones to India and will come equipped with missiles and other systems. The drones are for the Indian Army, Air Force and the Indian Navy and the qualitative requirements for the Indian Army and the Indian Air Force are in the process of being finalised.

As has been reported by the Financial Express Online that all the drones will have different configurations as the payloads required by each service is going to be different. According to sources, “The Acceptance of Necessity (AoN) is likely to be issued soon, once all the procedures are followed and completed in a time-bound manner.”

These drones are going to help the Indian Navy to expand its monitoring of the Indian Ocean and to further strengthen its surveillance of its coastal boundaries.

While the Indian Navy is already using the P-8i for the carrying out anti-submarine warfare, the Sea Guardian drones which will be armed with missiles and radars will be used for the maritime reconnaissance.

These drones will come through the Foreign Military sales route and agreement will be between the governments of India and the US and the San Diego based General Atomics. The drones for the Indian Navy will easily work in sync with the P-8i which is already in service. Since in 2018, the two governments had inked the Communications Compatibility and Security Agreement (COMCASA), the American platforms in the Indian armed forces will get encrypted systems and these will help in improving their capabilities.

Each fully armed drone with sensors and weapons is expected to cost $ 200 million, making it more expansive than a fighter plane.

As reported earlier, the naval variant of Predator –B drones from the General, Atomics has the capability to carry an external payload of 2.1 tonnes.

It can fly at an altitude of over 40,000 feet, with endurance of around 35 hours.

DRDO LASTEC is working on the state of art technology required for Pulsed Fiber Laser. In picture experimental setup for fiber laser .

Pulsed Fiber Lasers (PFLs) are rapidly replacing the conventional Q-switched bulk solid state lasers for generating nano second pulses at multi-kHz repetition rates. Such lasers are required for various long range applications like remote sensing, imaging, LIDAR, etc. Advantages offered by fiber based solutions include simpler thermal management, higher efficiency, flexible pulse format and waveguide defined beam quality independent of power level. Fully integrated structure in fiber laser provides compact, robust, alignment free laser that is compatible with highly efficient fiber pigtailed high power pump diodes and various fiber integrated devices such as FBG, fiber couplers, etc.

LASTEC has initiated work on this very challenging domain of developing different pulsed fiber laser sources involving Ytterbium and Erbium doped fibers to generate 1.0 μm and 1.5 μm wavelengths respectively at high repetition rates. These sources are required for long range applications like target illumination, dazzling, etc

A fiber laser is pumped by high power multi mode single emitter diode bars, typically through a cladding surrounding a single mode core. This single mode core is typically 5 to 12 μm in diameter. The double clad fiber consists of an inner single mode core doped with the appropriate rare earth ions such as Ytterbium, Erbium, Neodymium and Thulium. The cladding is made of undoped glass that has a lower index of refraction. The pump light is injected into the cladding and propagated along the structure, passing through the active core and producing a population inversion.

The emission wavelength is a function of choices in the doped fiber and by type of reflector, e.g. Bragg Grating. Traditionally, intense nanosecond laser pulses are generated with Q-switching techniques. However, a low power pulsed seed source, e.g. again switched laser diode may be employed whose output may be amplified to substantial energies with a fiber amplifier chain. With this approach one can easily change the pulse repetition rate and output pulse energy without changing the pulse duration, or can change the pulse duration and shape without affecting other pulse parameters. In a Q-switched laser, such flexible parameter control is not possible; e.g., lower pulse energy usually implies longer pulses.

Critical Areas

To get high beam quality, single mode waveguide structures are required. A small core clad numerical aperture is used to maintain the single mode transmission but it also leads to intense power density in a small core area, which brings strong nonlinear effects such as Stimulated Raman Scattering (SRS), Stimulated Brillouin Scattering (SBS) and Amplified Spontaneous Emission (ASE), which can limit the maximum output power of fiber lasers. The use of large core or Large Mode Area (LMA) fibers helps in reducing optical intensity and prevent these parasitic effects. Recently peak powers ~1 MW have been reported in combination with multi-watt average powers. The LMA in conventional fibers, however, leads to multimode propagation leading to degradation of beam quality. Therefore novel fibers called Photonic Crystal Fibers (PCF) have been the subject of intense research in recent years

Development of pulsed fiber laser sources would require several critical components with high damage thresholds to sustain high peak power densities. These components include LMA doped delivery fibers, high power pump laser diodes, isolators, pump combiners, couplers, filters, etc. Significant advances in high power diode pump lasers, refinement of power scaling and energy storage techniques, fiber component fabrication such as FBG are opening up the way for the development of active fiber systems that can deliver tens of watts of single transverse and longitudinal-mode output power, millijoule pulse energies, and ultra short pulses with peak powers in the 10-100 MW region.

Furthermore, advances in nonlinear optical materials are permitting these high-power fiber laser outputs to be efficiently converted to the visible and near infrared (IR) spectral regions. This would require Polarisation Maintaning (PM) components.

For the industrial, scientific medical and defence applications fiber lasers offer wide wavelength range. Availability of narrow line widths, polarized or unpolarised emissions, short pulse duration's, single mode operation, insensitivity to environmental conditions and compact size are some of the advantages only fiber lasers can accomplish.
