P. Lopez et al., Subarray weighting for the difference patterns of monopulse antennas: Joint optimization of subarray configurations and weights, IEEE ANTENN, 49(11), 2001, pp. 1606-1608
Given a linear antenna array with an excitation distribution affording a su
m pattern, subarray weighting allows the same array also to generate a diff
erence pattern, with minimal alteration of the signal feed circuitry. Previ
ous implementations of this approach have optimized the weights of given su
barrays. Here we report the simultaneous optimization of the partition in s
ubarrays and the subarray weights.
