Summary: 86 IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 48, NO. 1, JANUARY 2000
Compensation for the Effects of Mutual Coupling on
Direct Data Domain Adaptive Algorithms
Raviraj S. Adve, Member, IEEE, and Tapan Kumar Sarkar, Fellow, IEEE
Abstract--This paper investigates the effects of mutual coupling
between the elements of an array on direct data domain algo-
rithms. Mutual coupling severely undermines the interference
suppression capabilities of direct data domain algorithms. The
method of moments (MoM) is used to evaluate the mutual coupling
between the elements of a given array. The MoM admittance
matrix is then used to eliminate the effects of mutual coupling.
Index Terms--Adaptive arrays, mutual coupling.
I. INTRODUCTION
ADAPTIVE array techniques promise to be the best means
available to mitigate the effects of severe dynamic inter-
ference on the performance of airborne radar systems. The prin-
ciple advantage of an adaptive array is the ability to electroni-
cally steer the mainlobe of the antenna to any desired direction
while also automatically placing deep pattern nulls in the spe-
cific direction of interference sources.
