The technology for through-wall human detection with ultra-wideband (UWB) radar was discussed. Due to the large amount of UWB radar data, compressive sensing theory was introduced and compressed UWB radar data can be collected. The singular value decomposition algorithm was used to acquire the singular values of compressed radar data. The compressed UWB radar data were collected at two statuses...

GB-SAR (Ground Based Synthetic Aperture Radar) for inspection of wooden and concrete walls and structures has been developed and the system was evaluated by test measurements. The GB-SAR system uses frequency bandwidth 1-10GHz, and it can acquire full polarimetric radar signal. Then Synthetic Aperture (SAR) Radar signal processing is used to reconstruct 3-dimenatioal images of inner structure o...

We present joint optical-radar observations of meteors collected near the peak of the Leonid activity in 2002. We show four examples of joint detections with a large, phased array L-band radar and with intensified video cameras. The general characteristic of the radar-detected optical meteors is that they show the radar detection below the termination of the optical meteor. Therefore, at least ...

APhased MIMO radar with full waveform diversity is proposed which divides the transmit array into overlapping subarrays in such a way that the number of subarrays are equal to the number of transmit antennas. Each subarray send sout a unique wave form towards the target of interest and thus provides a full waveform diversity, which results in the virtual extension of received array. This virtua...

The designing of a continuous wave radar radar (CW) intended for remote counting of traf fic (remote traffic counter) and speed measurement of transport means with the help of high speed trajectories in the radar beam for long range transferring of these data is considered. It was experimen tally shown that, for recording the current number of transport means and measuring the speed of each of ...

Understanding the unusual radar scattering characteristics of sand dunes is necessary in the analysis of radar images of aeolian landscapes of the earth and of other planets. In this paper we report on airborne radar scatterometer data of sand dunes, acquired at multiple frequencies and polarizations. Radar backscatter from sand dunes is very sensitive to the imaging geometry. At small incidenc...

This contribution points out the potential of radar sensors with high resolution in azimuth and range in traffic environment and addresses some aspects of their practical implementation with respect to system design, hardware and software. A prototypical vehicle-based instrumentation radar is presented, which performs on-line acquisition and real-time visualisation of radar images with an updat...

Proudman Oceanographic Laboratory (POL) deployed an X-band (9.8GHz, 3cm wavelength) marine radar during the European COAST3D field experiments in Teignmouth, UK. The study site is a complex three-dimensional tidal inlet. A sequence of 64 radar images was collected at time interval of 2.25s every hour. Although realistic-looking wave patterns are observed in the radar images, it is still unclear...
