Abstract

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 of EIRP, signals radiated from each antenna should be coherently added in the destination and PHASE CALIBRATION between array elements is a critical issue. In this paper, calibration opportunities using satellites have been investigated. Location of phase center of array elements and location of satellites are taken into account and their effect on arrays with different sizes has been analyzed.
