Applicability of redundancy calibration on dense phased arrays

• We aim to have an efficient and computationally cheap calibration method for dense phased arrays or any array which has enough redundant baselines. The most recently developed calibration method, multisource calibration requires a sky model. This takes computational capacity of the array's processor, especially when an extended structure like the galactic plane is present. This occurs due to short baselines. Redundancy calibration is independant of sky model. This in addition to having sufficient redundant baselines in dense phased arrays are the reasons why we study this method throughly. In the following paper, initial results of the redundancy calibration on dense phased arrays will be presented. The results are significantly promising that keeps up motivated to pursue this method in more details later on.
