Abstract
An adaptive nulling communication system for nulling undesired signals from communication signals in multiple separate and distinct coverage areas is disclosed. The adaptive nulling communication system includes a phased array antenna having multiple receiving elements to form a single aperture for receiving multiple signals. A first set of beam forming networks coupled to the phased array antenna forms the multiple separate and distinct coverage areas. A distribution network coupled to the first set of beam forming networks distributes the signals received from these coverage areas. A nulling processor having a second beam forming network coupled to the distribution network weights and adjusts the second beam forming network in response to the undesired signals to null these undesired signals from the communication signals.
