dc.description.abstractIn the recent times, there have been diversified upsurge in the technology of RF receivers. The formation of accurate beam is a compelling facet of performance in radar and communication systems increased flexibility. The digital component of the beam forming is called Digital Beam forming (DBF), where it utilises a Digital mechanics for the forming of a beam. Cancellation of the jammer signal presence is a step for which a DBF is heavily relied upon. The pivotal competence of Digital beam forming is to sample and digitise the incident signal accurately which is incident on the aperture of the antenna. This thesis examines the design concepts of an antenna array and also the aspects of determining Angle of Arrival (AOA) associated in the radar systems. The evaluation of the approaching dispensation for a source is of prominence in Non-Comm field. In past few years, research on appropriate DoA estimation techniques has been a prime area for communication engineers. The field of data structure set of analysing and modifying signal can be categorised into self adaption signal analysing and energy spread in space. The distribution pattern of frequency in space domain exhibits the distribution in the complete hemisphere. In receiving mode, processing of the signal by digital means leads to formation of the beam known as signal processing of the array which gives the radar a flexibility to design/form a particular pattern of beam. The process of regulating beam forming process is done by providing corrective action on to the array weights as variations in the feed system, the antenna and the receiver channel in real time and simultaneously facilitating flexible control in formation of the beam pattern. The existence of jammer in the area of exercise is invalidated, leading to better output performance of the antenna assembly.en_US
