Abstract :
This research shows how a RSNS virtual spacing interferometer can be used to increase the resolution of a DF system. Computer simulations for both the real array and virtual arrays showed good tolerance to noise, channel errors, and element position errors. The processing resolution can be selected based on the emitterpsilas SNR.
