Excitation matching procedure for sub-arrayed monopulse arrays with maximum directivity

An Excitationmatching Procedure for Sub-arrayed Monopulse Arrays with Maximum Directivity

In this paper, the maximization of the directivity of compromise difference patterns in subarrayed monopulse linear array antennas with optimum sum mode is addressed by means of a two-stage excitation matching procedure. The knowledge of the independently optimum difference excitations, which provide the maximum directivity, is exploited with an efficient matching technique based on the contigu...

Synthesis of Sub-arrayed Monopulse Planar Arrays by Means of an Innovative Excitation Matching Method

Directivity Optimization in Planar Sub-arrayed Monopulse Antenna

In this paper, the Contiguous Partition Method (CPM) is applied to the optimization of the directivity of difference patterns in monopulse planar array antennas. Since the excitations providing maximum directivity of planar arrays can be analytically computed and because of the excitation matching nature of the CPM, the problem at hand is recast as the synthesis of the difference compromise sol...

Hybrid Approach for Sub-arrayed Monopulse Antenna Synthesis

Synthesis of Antenna Arrays of Maximum Directivity for a Specified Sidelobe Level

Linear and planar antenna arrays are synthesized to have maximum directivity for a specified sidelobe level. The directivity is maximized subject to a given SLL. The beamwidth and the zeros of array factor are studied as well as the directivity. Maximum directivity-arrays are compared through some examples with super-directive, uniform, Dolph-Chebyshev and Riblet-Chebychev arrays to find a comp...
