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...

Radars are vital systems for the navy as they are the primary systems for the detection, tracking and sometimes classification of friendly and hostile targets. It is therefore important that navies can assess the radar’s performance under the prevailing conditions. The atmosphere can significantly alter the radar’s performance from standard....

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...

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...

Due to the necessity of more sources of renewable wind generated energy, the number of wind turbines in the Netherlands has grown in the past. Unfortunately, big sizes and movements of the blades negatively impact ground-based Doppler radars in the form of Doppler clutter. Such clutter leads to a downgrade of the surveillance radar performance...

Terrain Referenced Navigation (TRN) refers to a form of localization in which measurements of distances to the terrain surface are matched with a digital elevation map allowing a vehicle to estimate its own position within the map. The main goal of this dissertation is to improve TRN performance through better signal processing. More...

In dit verslag gaan wij in op de aansturing van radar-hardware voor de detectie van mensen. Hierbij zullen de gebruikte radarmodules besproken worden, alsmede de functiegenerator die hiervoor gebruikt is en het ontwerp van de behuizing. De radarhardware maakt deel uit van een groter systeem, waarbij het de bedoeling is om mensen door middel van...

The rapid development of wireless communication systems and the subsequent burst of wireless devices place several demands on the antenna designs. In particular, the development of high-performance radio systems require the adoption of broadband antennas featuring low profile, high gain, embedded installation and reduced manufacturing costs....
