Laser Science and Technology Centre (LASTEC), Delhi, has developed a

Programmable PRF (Pulse Repetition Frequency) Code Laser Target Designator

for performing field checks and carriage trials of laser-guided bombs, projectiles

and missiles. The PRF code programmability in the range 5 to 50 pulses/s with time

interval resolution of 1µs allows field checks on a wide range of Laser seeker units of

varying specifications used in laser guided munitions. The system jointly developed

by EOCM and Optoelectronics Systems and Solid State Laser Divisions of LASTEC has been

completed successfully. The equipment has been field tested with indigenously developed laser

seeker kits as well as laser seeker kits of foreign make.

PATENT GRANTED

Copyrights Obtained

DRDO has been granted patent (Patent No. 218762) titled, An improved Externally-driven Flyback-type dc-to-dc

converter. The patent gives a new design methodology and circuit topology for design of externally-driven flyback-type dc-

to-dc converters. According to Shri AK Maini, Sci G at Laser Science and Technology Centre (LASTEC), Delhi, inventor of

the patent, the new topology is particularly relevant to design of capacitor charging units of flash pumped solid state lasers

used as laser range finders and target designators. The new circuit topology would lead to design of capacitor charging

units with much higher conversion efficiency, and consequently, higher wall plug efficiency for the above mentioned

battlefield laser systems.

Scientific Analysis Group (SAG), Delhi, has received copyrights for two developed software packages named

SAMEEKSHA and HASTAKSHAR under the project PAT CLAN.

SAMEEKSHA: (Copyright No. SW-3714/2007); consists of 32 software meant for extracting features from cipher

text, statistical analysis of word combination and pattern word analysis. Dr Shri Kant, Sci F (Project Leader), Ms

Neelam Verma, Sci F, and Ms Anita Dwivedi, TO B are the contributors.

HASTAKSHAR: (Copyright No. SW-3715/2007); consists of 10 software for selecting prominent features to be

used in various classification models. It also addresses the issue of Curse of Dimensionality in Pattern

Recognition Problems. Dr Shri Kant, Sci F (Project Leader), Ms Neelam Verma, Sci F, Shri Rajesh Asthana, Sci C,
