Dual Frequency And Low Cross-Polarised Antennas For Synthetic Aperture Radar
Currently most of the synthetic aperture radar (SAR) systems operate with two separate antennas. The weight, size and space for two antennas greatly increase the cost of the SAR mission. However, single antenna is typically limited to single-frequency, single-polarisation applications. In this work,...
