Cirrus clouds play an important role in the Earth’s radiation budget. The transfer of radiation through ice cloud layers depends on the particle phase, concentration, size distribution, and the cloud thickness and shape. Consequently, for reliable simulations of present and future climate using General Circulation Models an accurate representation of ice cloud properties is essential. This give...

The performance of frequency modulated continuous wave (FMCW) radar in tracking targets is presented and analysed. Obstacle detection, target tracking and radar target tracking performance models are developed and were used to investigate and to propose ways of improving the autonomous motion of unmanned surface vehicle (USV). Possible factors affecting the performance of FMCW radar in tracking...

This study assesses the feasibility of radar-based remote sensing of barometric pressure of the air at the sea surface. Currently, sea surface barometric pressure measurements can only be obtained from in situ observations including buoy and dropsonde measurements, which are sparse in spatial coverage and expensive to implement. There are no operational remote sensing methods available even in ...

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 ...

Radar technology was designed to increase public safety on sea and in the air. Today radars are used in many fields of application, such as airdefense, air-traffic-control, zone protection (in military bases, airports, industry), people search and others. Classic pulse radars are often being replaced by continuous wave radars. Unique features of continuous wave radars, such as the lack of ambig...

Within the High Resolution Air-Sea Interaction (HiRes) DRI the Center for Maritime Research and Experimentation (CMRE), former NATO Undersea Research Center, will develop and validate methodologies to retrieve wind field parameters from X-band marine radars. The main parameters are the mean surface wind vector; the high-resolution wind field, as well as wind gusts in vicinity of the measurement...

Besides the well known microwave radar systems mainly used in navigation, surveillance, and control applications, High-Frequency (HF) radars gain increased attention during the last decades. These HF radars are operated in the 3-30 MHz frequency range and due to ground-wave or sky-wave propagation provide over-the-horizon (OTH) capabilities. Many of these OTH radars apply frequency modulated co...

We describe radar measurements of waves, currents and winds made on the coast of northern Scotland during two 2013/14 winter storms, giving methods, results and interpretation. Wave parameters (height, period, direction and short-wave/wind direction) were derived and compared with measurements made by a neighboring buoy and local weather stations. Wind direction and current velocity maps were p...
