Emitter Geolocation — CASDIC, DRDO

Duration: May–June 2025

Overview

Industrial internship at Combat Aircraft System Development and Integration Centre (CASDIC), DRDO. Developed MATLAB simulation for aircraft–radar interaction and emitter localization.

Technical Work

• LLA ↔ ECEF coordinate transformations
• Roll–Pitch–Yaw modeling
• Rotation matrices (Body/ECEF/Sensor frames)
• Azimuth & Elevation computation
• Newton–Raphson & Gauss–Newton algorithms
• Least-Squares triangulation
• AWGN noise modeling

Laboratory Exposure

Observed antenna testing labs including microstrip, horn and array antennas. Visited anechoic chamber for radiation pattern measurements.

Software Used

MATLAB (Aerospace Toolbox, Mapping Toolbox, Phased Array System Toolbox, App Designer).
