1. Evaluation of FMCW Radar Jamming Sensitivity
University essay from Uppsala universitet/Signaler och systemAbstract : In this work, the interference sensitivity of an FMCW radar has been evaluated by studying the impact on a simulated detection chain. A commercially available FMCW radar was first characterized and its properties then laid the foundation for a simulation model implemented in Matlab. READ MORE

2. Examining the Effects of AWGN Jamming on a Tactical Data Link Communication System
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : This master thesis investigates the jamming of Tactical Data Links (TDLs). The goal is to make a model that is capable of giving an overview of a communication system under jamming conditions, offering the user a suggestion for the best coding scheme and modulation to use in any given situation.

3. The Effect of Distortions Induced by Adaptive Antenna Arrays in GNSS Applications
University essay from Linköpings universitet/Kommunikationssystem; Linköpings universitet/Tekniska fakultetenAbstract : Global Navigation Satellite Systems (GNSS) are vital tools for accurate navigation and timing for both civil and military use. Due to the low power of the GNSS signals, these systems are sensitive to interference attacks. For wideband GNSS jamming, adaptive antenna arrays are commonly used to suppress interference. READ MORE

4. Time Synchronization of TDOA Sensors Using a Local Reference Signal
University essay from Linköpings universitet/KommunikationssystemAbstract : Synchronization of distributed time difference of arrival (TDOA) sensor networks can be performed using reference signals from GPS satellites. This method provides high accuracy, but is vulnerable to jamming, and is not reliable enough to be used in military applications. READ MORE

5. Unmanned Aerial Vehicle Positioning Using a Phased Array Radio and GNSS Independent Sensors
University essay from Linköpings universitet/ReglerteknikAbstract : This thesis studies the possibility to replace the global navigation satellite system (GNSS) with a phased array radio system (PARS) for positioning and navigation of an unmanned aerial vehicle (UAV). With the increase of UAVs in both civilian and military applications, the need for a robust and accurate navigation solution has increased. READ MORE
