Minimum Redundancy Array Structure For Interference Cancellation, Wan-Ling Chen
Minimum Redundancy Array Structure For Interference Cancellation, Wan-Ling Chen
Dissertations
Adaptive antenna arrays are widely used in many advanced radar, sonar, and communication systems because of their effectiveness in cancelling intentional or unintentional interferers. A uniformly spaced linear array, referred to as a Uniform Regular Array (URA), is the usual structure used for interference cancellation. The Minimum Redundancy Array (MRA) structure proposed in this work is a special kind of thinned array whose application was limited in the past to direction finding. MRAs with the same number of array elements can resolve directions of much more closely spaced signals than URAs.
The URA structure is customarily utilized for interference cancellation, …
