A review of the use of millimetre wave radar for robotic applications is presented. The paper includes a brief overview of the different radar and scanner technologies that are available and finishes with a review of some of the techniques that can be used to represent and use radar data.

We aim to assess the feasibility of wireless over fibre systems that can operate at millimetre-wave frequencies for delivering gigabit/s wireless data to portable or fixed customer units. We have demonstrated the error-free transmission of 1 Gbit/s D-BPSK signals over 2.2 km of single-mode fibre and over 2 metres of RF cable in the 40 GHz band.

In this paper, an extension of the discrete Radiative Energy Transfer (dRET) model to include time-variant channel effects in vegetation media at millimetre-wave frequencies is presented. The proposed model uses the dRET to estimate the signal mean level, and uses appropriate stochastic signal distributions to estimate the dynamic (time variant) radio channel effects using appropriately extract...

in this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave rof) system that uses a dual drive mach zehnder modulator (dd-mzm), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. the input to the dd-mzm are binary phase shift keying (bpsk), quadrature phase shift keying (qpsk), 8-phase shift keying (8-psk) and...

N this project, new architectures in the field of imaging radiometry are developed. A key component in such radiometers is the receiver front-end. The project concentrates on the design of innovative receiver structures that are based on the so-called self-oscillating mixing technique. Self-oscillating mixers are an excellent choice for low-cost modern receiver architectures, because both the o...

results of velocity structure modeling in the earth's crust using a comparison approach of receiver function analysis and joint inversion of receiver functions with surface wave dispersion data are presented in this paper. seismograms of the teleseismic events that have been recorded on a broadband seismic station in the central alborz were used for data processing. velocity models that we...
