Abstract

A spread spectrum phased array receiver has a set of phased array antennas. The set of phased array antennas receive a spread spectrum signal containing a plurality of channels. The receiver outputs timed versions of the received signal. Each timed version is associated with a respective one out of the set of phased array antennas. A plurality of despread signals is produced by despreading each timed version of the received signal using a plurality of chip code sequences associated with the channels. The despread signals are combined as a despread signal. A magnitude of the combined despread signal is determined for obtaining a present and a prior magnitude. The present and prior magnitude are compared. A delay associated with the timed versions is adjusted in response to the comparison so antenna beams are steered towards components of the spread spectrum signal with a highest combined magnitude.
