Abstract
An improved signal generator and method for radio navigation in accordance with systems of the type in which location is determined in accordance with radio fixings with respect to multiple points of reference, each of such points providing a coded transmission. Multiple coded bit sequences are stored in an adddressable read only memory. Phantom signals comprising a plurality of coded sequences are generated by addressing the memory in accordance with preselected sequences. Further, predetermined phase shifts are applied to the coded sequences to facilitate signal detection and associated computational processes.
