| titleOfInvention | Jamming suppression of spread spectrum antenna/receiver systems |
| abstract | A jamming suppression system which includes a plurality of receivers for receiving electromagnetic radiations and a separate notch filter couple to each receiver for filtering selected frequencies from electromagnetic radiations received by each of the receivers. In accordance with one embodiment of the invention, a spatial combiner responsive to the outputs of each of the notch filters extracts essentially jam-free information from the electromagnetic radiations. In accordance with a second embodiment of the invention, a plurality of spatial combiners, each responsive to the outputs of each of the notch filters, extracts essentially jam-free information from the electromagnetic radiations. The notch filters are adaptive notch filters for on-line selection of their filtering action. One of the notch filters is a master filter and the remainder of the notch filters are slave filters controlled by the master filter. In both embodiments, spatial filtering action is accomplished using a generalized sidelobe canceler that permits gain (relative to an isotropic antenna) to be preserved in the direction of one or more satellites while casting spatial mulls in the directions of inadvertent friendly or hostile jamming signals. |
