Ishwardat, N.K.S. (author)
During this thesis research an attempt is made to introduce a computational lightweight horizontal wind retrieval method applied on scanning Doppler radar velocity data. Horizontal wind parameters are the wind speed and wind direction. If know they are known in a vertical extend, they form a wind profile. In a typical approach, horizontal wind...

In FMCW radar systems, spectral estimation methods are used to determine the beat frequency of the reflected signal in order to obtain information about the range of scatterers relative to the position of the transmit/receive elements. Array processing techniques take advantage of the phase shifts per element and likewise use spectral estimation...

Modern automotive radar operates at the mm-wave frequency band and has to provide reliable sensing information about surrounding targets in all weather conditions. The aesthetic requirements for the modern car design and needs for mechanical protections result in the installation of radar sensor behind different types of plastic cover like the...

For the radar systems using phased array antennas it is important to understand how the reduction of mutual coupling between antenna elements can improve antenna scan performance. In order to perform this analysis one has to focus first on the physical phenomena and the structures that might decrease the mutual coupling. Among various approaches...

Phased array antennas require a distance of the array elements to be smaller than half a wavelength in order to avoid grating lobes while scanning through the whole visible space. In the case of planar dual- or multi-band antenna arrays, the capability of wide-angle scanning at the operational bands defines strict constraints on the electrical...

A frequency-pattern reconfigurable antenna based on a foreshortened non-radiative dielectric (NRD) waveguide structure with a tunable liquid crystal dielectric is proposed. The antenna operates within the full range of the unlicensed 60G-band. The antenna is fed by a stripped semi-rigid coaxial feed that is inserted directly into the liquid...

Gourova, R.N. (author)
The main problem discussed in this Thesis is waveform design for compressive sensing radar. Radar systems are used for a variety of different applications ranging from medicine to underground detection. The choice of waveforms determines the capabilities of the radar to distinguish between different closely spaced targets and frequencies. If...

During the period 2007-2011, the Microwave Sensing, Signals and Systems (MS3) division of TU Delft developed PARSAX, a high resolution FMCW research radar. Since it moves relatively slow, and it cannot utilize techniques such as monopulse or conical scanning, it is unable to track aircraft by itself. An external source of information is needed,...

The Technical University of Delft has started a project in the form of a Master Thesis to improve their existing and develop new algorithms for processing the measured data with the PARSAX radar for 2D-Windfield monitoring. A new algorithm is developed that detects and estimates the multi-layered structure of a windfield using the measured...

Current methods for concealed weapon detection are mainly used at stationary security check-points due to complexity and other serious limitations for real-time outdoor scenarios. A mobile imaging radar is considered as a proper solution for fast screening of people at mass events because of its ability to detect both metal and non-metal weapons...

Automatic detection of humans is an important part of many security and surveillance applications. Automatic processing diminishes the effect of human errors on the detection and allows extensive analysis after detection. Radar has certain advantages for human detection because of its all-weather and day and night capability, as well the fact it...

Azodi, H. (author)
Ground Penetrating Radar (GPR) is a promising technology to detect buried objects beneath or near ground surface. To achieve high-resolution and accurate enough images, the transmitting antenna (TX) in this technology is required to radiate a highly-correlated narrow width pulse towards ground where the targets are hidden. For this application,...

Due to its numerous applications, the problem of Direction-Of-Arrival (DOA) estimation of one or more incoming radio signals has attracted great attention in industrial and scientific research communities. Direction finding systems have been widely employed in civil and military applications, e.g. for navigation. However, due to recent wide...

In this thesis, image processing algorithms are applied to 3D GPR images, in order to improve the detection capabilities of a radar system. Detection based on the magnitude of the reflected signals may miss weak targets. On the other hand, an analysis of the texture properties of a target, i.e. the repeating pattern all over the surface, which...
