detection of stealth targets calls for employment of high-power radars which itself relies on usage of high-gain antennas like large parabolic reflectors. in the past few years, using of an array with many small reflectors instead of a large reflector antenna has been considered. this method provides enhanced eirp by a factor of n2 where n is the number of array antennas. regarding improvement ...

A null steering GPS antenna array is designed in this paper. In the proposed method, the exact full wave antenna radiation properties with the effect of mutual couplings and nearby scatterers are considered to calculate the array steering vector, precisely. Although the proposed method is not constrained by the array geometry and the antenna element specifications, a five patch antenna elements...

Abstract Hydrogeophysical assessment of aquifers in the Upper Denkyira East and West Districts Ghana has been carried out for groundwater potential protective capacity overburden rocks determination. The data study were obtained from Regional office Community Water Sanitation Agency (CWSA), Cape Coast. A total thirty-seven VES probed using a Schlumberger array with maximum current electrode spa...
