2006 International Conference on Software in Telecommunications and Computer Networks, 2006
The paper deals with the radar antenna modelling using NEC Win package. Obtaining radar antenna radiation model was necessary so one can later use it for calculation of radiation strength and estimation if there is any potential radiation damage to instruments that should be used for measuring radar antenna radiation.

Journal of the Franklin Institute, 1995
Abstract This paper reviews some of the current interests in radar antennas, including work conducted at the U.S. Naval Research Laboratory. Almost all types of antennas have been used in radar, but it is the phased array which has received the most attention in recent years, especially for military applications. Methods for making phased arrays more

Magnetic Antennas for Ground Penetrating Radar
The concept for a novel new antenna design is presented and investigated for application to ground penetrating radar (GPR). The proposed new antenna design is called the shielded magnetic bowtie antenna (MBA). As the name suggests, it is predominately constructed from a bowtie-shaped volume of magnetic material that is fed from the centre of the ...openaire +2 more sources
Ultrawideband array antennas for radars
2006 First European Conference on Antennas and Propagation, 2006The paper presents the results of investigations of array antennas intended to radiate high-power pulses of nanosecond and subnanosecond length. The array element is a combined antenna optimized for a given length of the exciting voltage pulse. Linear array antennas were investigated by the radiation wave beam in the steering mode.

The susceptibility of radar search antennas to radio-frequency interference (RFI) is determined to a great extent by the minor lobe structure. The use of detailed, three-dimensional patterns to predict RFI is not practical because the fine structure of the antenna pattern changes with frequency, range in the Fresnel zone, and site effects.
