Claim:
1. A monopulse radar system comprising: an antenna array comprising a plurality of sub-arrays operatively arranged in a first direction, each of the sub-arrays comprising a plurality of antenna elements grouped as a first group and a second group adjacent to each other in a second direction substantially perpendicular to the first direction; a plurality of transmit/receive (T/R) modules; and a processor, the T/R modules of the plurality of T/R modules being respectively coupled to the plurality of antenna elements, and configured to enable the antenna elements of the first groups and to disable the antenna elements of the second groups of a plurality of first sub-arrays from among the plurality of sub-arrays to form a first monopulse antenna, and to enable the antenna elements of the second groups and to disable the antenna elements of the first groups of a plurality of second sub-arrays from among the plurality of sub-arrays to form a second monopulse antenna, the processor being configured to perform monopulse processing to detect a position of a target in the second direction using the first monopulse antenna and the second monopulse antenna.
