Phased array technology has brought revolution not only in the defense but also in the commercial industry. Considering the development taking place in this area, it can be safely said that the future belongs to the phased array technology. This paper presents system level modeling and integration of the front end of phased array radar. This includes the modeling and simulation of an antenna array, transceiver (TR) module and the target detection. Concept of beam formation and steering is also explained with the help of simulation. The system level modeling is carried out in Advance Design System (ADS) and Momentum - an Electromagnetic (EM) tool of ADS. An effort in the simulations is made towards the realization, understanding and highlighting the challenges involved in the practical implementation of the system.
