Zusammenfassung:This article describes and examines a method of spatial suppression of extremely strong interfering signals (ISs) capable of complete desensitization and even damage of victim receivers' input circuits. This method not only protects victim receivers but also allows them to reliably receive desired signals in the presence of such ISs, using adaptive hybrid nulling whose first stage is performed at the receivers' analog inputs and the second stage is carried out in the receivers' digital portions.
