This thesis presents the design, analysis and test results of a 1.445 GHz Frequency-Modulated Continuous Wave (FMCW) collision-avoidance radar for Unmanned Aircraft Systems (UASs). This radar system is being developed by the department of Electrical Engineering (EE) in coordination with the Aerospace Engineering (AE) department and is intended to provide situational awareness for a 40% Yak-54 m...

Synthetic aperture radar (SAR) specializes in capturing two-dimensional images of Earth’s surface. Because satellites or aircraft have mainly been used as SAR platforms, pulse systems with high peak transmitted power preferred for long-range detection. However, because based on are generally too heavy and expensive, lightweight low-cost frequency-modulated continuous-wave (FMCW) attracted incre...

In the recent years, the radar technology, once used predominantly in the military, has started to emerge in numerous civilian applications. One of the areas that this technology appeared is the automotive industry. Nowadays, we can find various radars in modern cars that are used to assist a driver to ensure a safe drive and increase the quality of the driving experience. The future of the aut...

In view of the advantages of the Sine plus Noise FMCW radar over short range, in this paper, we presented a novel liquid height measuring system based on it. The principle of this system is analyzed in detail. Considering the liquid to be measured usually with high volatility, temperature, pressure, causticity or toxicity, we utilize trihedral corner reflector floating on the liquid to enhance ...

This paper proposes a FMCW radar transceiver with photonic elements. The proposed system is efficiently designed by budget analysis, and wideband signal generated using To verify the performance of system, field tests including changes in bandwidth are conducted. results confirm that resolution ISAR images improves as increases expected through analysis.
