PERFORMANCE ANALYSIS OF LINEAR ARRAY ANTENNA IN RADAR SYSTEM THROUGH ANALYTICAL METHOD AND COMPUTATION METHOD VIA DFT
It is imporlant to design RADAR antennas with more energy radiated in some parlicular directions and less in other
directions. Different types of antennas and their radiation patterns are evaluated. This is tantamount to requiring
that the radiation pattern should be concentrated in the actual direction of interest. This is hardly achievable with a
single RADAR antenna which has a specific radiation pattern. But with the use of the several antennas working
together, it is possible to improve the radiation according to suit some specific requirements. In this study we have
dealed with the most common linear array antenna. The equation of the electric field radiation pattern is derived
with detail discussion on array tapering. Simulation result shows the radiation pattern in one direction with lowered
side lobes, indicates the improvement of the wave propagation through the RADAR antenna.
