The radar chart approach is one of a number of special analytical tools that have been developed in connection with benchmarking in the private and public sectors. Although well established as a management tool, the radar chart approach has to our knowledge never been applied to benchmarking labour market performance. This paper assesses the usefulness of the radar chart approach in this policy...

In lunar exploration, spaceborne high frequency (HF) radar sounder is an effective tool for investigation of lunar subsurface structure in lunar exploration [1] [2]. The primary strategy for radar sounder detection of subsurface structure is through the time delay and intensity difference of the lunar surface and subsurface nadir echoes (Figure 1). It is important to fully understand electromag...

This paper presents a systematic scheme for fusing millimeter wave (MMW) radar and a monocular vision sensor for on-road obstacle detection. As a whole, a three-level fusion strategy based on visual attention mechanism and driver's visual consciousness is provided for MMW radar and monocular vision fusion so as to obtain better comprehensive performance. Then an experimental method for radar-vi...

This study presents a two-dimensional variational approach to retrieving raindrop size distributions (DSDs) from polarimetric radar data in the presence of attenuation. A two-parameter DSD model, the constrained-gamma model, is used to represent rain DSDs. Three polarimetric radar measurements, reflectivity (ZH), differential reflectivity (ZDR) and specific differential phase (KDP), are optimal...

The sequential algorithm for target detection in impulse environment by K-stage processing in polar Hough (PH) space is investigated. This algorithm permits the search radar to minimize the time of target detection, because the sequential detector used minimizes the number of the necessary radar antenna scans, while the conventional detector uses a fix scan number. The aim of our study is to mi...
