Title Realization of a Coherent Low Noise Receiver Module for the Integration in an Imaging Ka Band MIMO Radar Responsibilities: • Design an eight way local oscillator (LO) distribution network in ADS at 8.4 and 8.8 GHz for transmitter and receiver radar • PCB design of LO distribution network using Altium Designer (Schematic and Layout entry) • Realization and integration of 8 receive channels to form a receiver module for the Imaging Ka Band MIMO Radar

• Developed an automated test bench setup to facilitate the test and measurement(T&M) of RF components • Assembled evaluation board for amplifiers, low pass filter, and mixers • Developed measurement test scripts that determine the figures of merits, namely s-parameters, isolation, conversion gain, TOI, 1 dB compression point etc • hands-on experience with measurement equipment(s) namely Network Analyzer, Spectrum Analyzer, Power sUpply, Oscilloscope, and Signal Generator

• Performed measurements of slant range distance using Distance Measuring Equipment (DME) where the monitoring parameters were System Delay, Pulse Spacing, Efficiency, Power Output, Pulse Width and Pulse Shape. • Studied various NAV AIDS such as Visual, Astronomical, Navigation by dead rocking and radio navigation and DVOR (Doppler VHF Omni Range) • Range measurements using Primary and Secondary Radars

• RF Systems • Antenna Engineering • Radar Systems • Mobile Radio Networks 1 & 2 • Principle and Architectures of Cognitive Radio • Signals, Systems and Communication • Information Theory and Source Coding
