Systems and method for placing nulls at desired locations within a beam pattern of a phased array antenna are provided. According to embodiments of the present disclosure, a weight vector solution for controlling operating parameters of the M elements of the array antenna such that a beam pattern incorporating one or more desired nulls is obtained by performing operations on an N×N matrix, where N is equal to a number of vectors used to describe the nulls. The nulls can be placed at arbitrary locations within the beam pattern, and can be formed with arbitrary depths.

Efficient deterministic nulling method and apparatus

Wide band adaptive beam forming methods and systems are provided. The beam forming methods can include receiving signals at multiple antenna elements and digitizing samples of the received signals for some period of time. The samples are divided into sub-channels according to frequency, and interferers are identified as signals appearing across at least some minimum number of the sub-channels. After removing signals not identified as interferers from the collected signal information, that information is used to calculate weights for forming a beam having a null at the identified location of the interferer. The beam forming systems include multiple element antennas having arms in the form of a spiral, and processing hardware for performing adaptive beam forming.
