Abstract

The VHF/UHF band radar that using circular array antennas is a novel kind of radar, whose performances, such as angular accuracy, angular resolution, anti-jamming and low-altitude coverage capabilities are better than the conventional VHF/UHF band radar. On one hand, we focus on how the directivity of array element will influence upon the array pattern. The performance characteristics of the single microstrip patch antenna can be further enhanced by using microstrip patch antenna array. On the other hand, in order to lower the side lobe level (SLL) of circular array antennas , we investigate the effectiveness of amplitude-weighted methods including Taylor Window and Gaussian Window.
