Abstract

Phased array radar is very important in modern radar development, and multiple digital beams forming technology is the most significant technology in phased array radar. Beam forming is a signal processing technique used in antenna arrays for directional signal transmission or reception. Digital multiple beam forming on each antenna element about large phased array radar is impossible in processor based digital processing units, because it needs simultaneous processing many A/D channels. In this project we resolve this problem by using a multi array based beam forming technique with multiplexed signal processing unit on FPGA. The conventional technique of completely duplicated hardware and also dynamic reconfiguration does not yield the real time parallel beam processing. The proposed technique employs multiplexed signal processing unit which is time shared for various beam formers. This technique provides simultaneous beams without any compromise on functionality.
