Abstract : A new technique for improving the operation of a interference suppression system, particularly in a side-lobe canceller system, against multiple interference sources. A plurality of auxiliary receiving antennas, providing interference signals to side-lobe canceller loops, are spaced about a main directional receiving antenna and positioned to preferably form a configuration such that no lines of sight through any two auxiliary antennas are collinear or parallel to a line of sight through any other two auxiliary antennas. The configuration is then arranged relative to the main antenna such that no lines through any two auxiliary antennas are substantially parallel with the primary direction of a multiple jammer attack.
