The design of a 94 GHz high resolution coherent radar
… GHz short pulse, low duty cycle, high resolution coherent injection locked radar system for sensor applications, with the specific use as an early warning radar ,against high voltage transmission lines. The recent development of solid-state components for frequencies around 94 GHz has made it …

Sea surface wave reconstruction from marine radar images
The X-band marine radar is one type of remote sensing technology which is being increasingly used to measure sea surface waves nowadays. In this thesis, how to reconstruct sea surface wave elevation maps from X-band marine radar images and do wave field prediction over short term in real time are …

Enabling and directing real-time cognitive radar transmitter optimization.
… inflexible methods. Among these users are radar systems, which have historically been allocated large sections of bandwidth. In order to adapt and coexist with new technology in a dynamically managed environment, next generation radars must be able to adjust their spectral configuration in …

Time and Frequency Transfer in a Coherent Multistatic Radar using a White Rabbit Network
Networks of coherent multistatic radars require accurate and stable time and frequency transfer (TFT) for range and Doppler estimation. TFT techniques based on global navigation satellite systems (GNSS), have been favoured for several reasons, such as enabling node mobility through wireless …

Contributions towards a coherent chaotic oscillator at 100MHz and 70 GHz antennas for automotive radar applications.
This Master's thesis focuses on the design of a coherent chaotic oscillator working at a base frequency of 100MHz, and the design of an array of patches operating in the frequency range of 71-76 GHz. The array will be used to transmit the chaotic signal after it is up-converted. The requirements of …
