PULSED, PSEUDO-RANDOM POSITION FIXING RADIO NAVIGATION METHOD AND SYSTEM AND THE LIKE This disclosure is concerned with a technique and apparatus for reducing CW and other inband interference in a broad bandwidth RF pulse navigation system to inobtrusive noise through the use of pulse-position random modulation, including, where desired, superimposed random phase modulation, with signal-random modulation code cross-correlation in reception.
