Abstract
A novel range based acquisition system includes a receiver for receiving PN encoded signals coupled to a novel range based variable dwell correlator which detects and acquires uniquely timed received transmitter PN encoded signals employing different search dwell times for each of the estimated ranges from which the receiver transmitted PN encoded signals are being propagated so as to enhance the speed of acquisition of said PN encoded signals.
