In the maritime boundary layer, air-sea interaction processes have an important impact on radar propagation. The radar range performance near the sea surface depends on meteorological and sea surface conditions. Strong gradients of humidity and tempe

This paper addresses an experiment that was carried out in the North Sea region in the area of the island of Sylt with the aim to study the influence of the maritime boundary layer (MBL) on the propagation of radar signals under low grazing angle geo

The radar signature of power lines is of high importance in the design of systems for helicopter collision avoidance. Laboratory measurements have been reported previously, but field measurements at millimeter waves are missing. The present contribut

Helicopter collision avoidance sensors require all weather and day and night performance. Radar fulfills these conditions. To be able to see also cables and other small scale structures, millimeter wave radar is a favourite candidate for this task. T

Radar propagation near the sea surface depends on meteorological conditions and sea surface roughness. Often strong gradients of humidity and temperature can be observed close to the air-water interface leading to abnormal propagation effects such as

In this paper two RCS prediction codes were investigated with respect to their applicability at millimeterwave radar bands. Two classes of land-targets, anti-tank mines and a jeep, were measured at two frequencies and afterwards the RCS calculations

Different types of anti-tank surface mines were measured on a turntable in a n anechoic chamber, and modelled with the German SIMPRASS model. In addition, several flights over a realistic minefield were performed with a 35 GHz and a 94 GHz radar oper
