Abstract
In Remote-sensing and high resolution image application, the use of the synthetic aperture radar (SAR) has increased manifold. To achieve high resolution in range, the instantaneous bandwidth requirement is very large (>20 % for 10 GHz). The active electronically scanned array (AESA) antenna, which utilizes the narrow band width phase shifter, suffers from 'beam-squint' phenomenon i.e. beam direction of the array changes across the instantaneous bandwidth. For applications with large bandwidth and high frequency requirements, true time delay beam-forming is a promising candidate. The true time delay units are expensive and bulky. This paper presents the tradeoffs in considering the distribution of true time delay units of phased array with reference to its performance of side lobe level, gain etc.
