    Abstract : This master’s thesis covers the design and implementation of a monopulse directionof arrival (DOA) estimation algorithm on an FPGA. The goal is to implement a complete system that is capable of estimating the bearing of an incident signal. READ MORE

  6. 10. Direction Finding : Determine the direction to a transmitter with randomly placed sensors

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Fernando Franzén; [2019]
    Keywords : Direction Finding; TDOA; MUSIC; UCA; Random Array; DOA;

    Abstract : There are a lot of stand-alone and mobile platforms using transmitters today. Some want to be found while others do not. In our modern society there is a great demand of mobility and communication abilities. This means that several mobile platforms could potentially carry a sensor to record incoming signals to be used in Direction Finding. READ MORE
