My Work

# DRFM based Active Radar Simulator: (Work in Progress)

Client: National Instruments, India

Environment: Ni Lab-view, Labview FPGA RIO, Radar, HFSS, MATLAB etc.

Team Size: 3

Role: Sr. Project Engineer

Project Description:

Design and Develop a real time radar simulator to confirm the correctness and performance of receiver

system, in laboratory environment. This system will provide virtual environment to radar receiver. System

has DRFM to capture the signal from radar transmitter and retransmit after operating. T he simulator is

proposed with arbitrary numbers of scatterers, reflectors with complex geometry and will support pulsed

and continuous wave (CW) radar systems. These parameters will provide a realistic simulation given a real

target or hostile environment that the radar or EW system will be operating.

Responsibilities and Contribution:

Developing the DRFM (Digital RF Memory) using NI Labview FPGA. DRFM includes signal capturing,

introducing targets (delay, clutters, doppler etc), retransmission. Testing of signals using vsa (pxi), signal

analyzers, generators etc. Designing and Simulation of both radar antenna and DRFM antenna with their

radiation pattern using EM simulators.

# Conceptualization and Design of Free Space Microwave Measurement Facility:

Client: Defence Research and Development Organization (DRDO), Jodhpur

Environment: HFSS, CST, MATLAB, Antenna Design etc.

Team Size: 2

Role: Project Engineer

Project Description:

Development and Optimization of Free Space Material Measurement Facility for C, X and Ku band. The

system has three pairs of Lensed Horn Antennas for above three bands . The spot-focusing antennas are

typically feed horns fitted with lenses over their apertures. The radiation from the lens antennas can be

modeled as Gaussian beams. The Gaussian beam from the tran smit horn is made to focus at the center of

the system, and the diverging beam is then refocused at the second horn. This phenomenon creates a

Gaussian plane wave midway between the two lenses. The sample under test is placed at this location,

which allows the use of plane wave theory in order to extract the material properties. GAIN ~ 24.4 dB,

VSWR < 1.28, S11 < -17dB.

Responsibilities and Contribution:

Conceptualize aperture antenna and dielectric lens according to bands, calculate all design parameters and

dimensions using MATLAB. Design the system using calculated dimensions on different 3D EM simulators

then optimize as per desire.

# Design of Circular Waveguide To Coaxial Transition And Dipole Probe for E-Field Measurement:

Client: Defence Research and Development Organization (DRDO), Jodhpur

Environment: HFSS, CST, MATLAB, VNA.

Team Size: 2

Role: Project Engineer

Project Description:

Development and optimization of circular to rectangular waveguide transitions for C, X and Ku bands. The

horn antennas of different inlet circular aperture size need different transitions to feed from their standard

sources.(Circular -> Rectangular -> SMA ). Also Development of a Probe system to measure relative

magnitude of electric field in a plane for free space material characterization system.

Responsibilities and Contribution:

Conceptualize transitions and probe for all three bands. Design and simulate on EM 3D simulators then

optimization and testing. Create configuration documents for vendors.

# RF/Microwave Antennas:

Client: B.tech, M.Tech, Phd students

Environment: HFSS, CST, EMPro, ADS, VSA, Network Analyzer, MATLAB etc.

Role: Sr. Project Engineer

Project Description:

Different projects on antenna / component designing like pifa, helical, patch antennas etc for students and

their compulsory degree programs.

Responsibilities and Contribution:

Design to create reference model then test and verify designs made by students. Perform Simulations and

optimization. Report to professor.

Projects Under Taken During Degree:

GSM controlled home appliances.

Wireless Power Transfer.

GSM mobile Jammer.

Sort range Mobile phone detector.

An Intelligent FM broadcasting system (Final year project, for college campus)

Wirelessly controlled Robotic-Arm.

RF Controlled Home-Appliances. (upto 2048, simultaneously with single remote)

Home Automation System using microcontroller.

Wireless Stepper Motor controller using LPT port.

Automatic Railway Gate control system.

A line follower Robot with and without microcontroller.

Fire Alarm system.

Technical Degree

Bachelor in Technology (B.Tech) in Electronics and Communication Engineering.

Other Interests

Just pick a wasted electronic instrument and try to repair it.

Hardware Disassembling and Assembling.

Mobile Phone Repairing. (yes I do )

Reading Books etc.
