Abstract

In view of difficult C/N0 measurement of GPS signal under oppressive jamming, C/N0 characteristic of GPS signal under oppressive jamming and form of oppressive jamming signal in I channel and Q channel of GPS receiver were analyzed, the method for measuring C/N0 in signal channel under oppressive jamming was put forward, as a result, the error of C/N0 calculation was reduced. With this method, GPS receiver could carry out C/N0 measurement during signal capture without hardware expansion; furthermore, the measuring process is simple, effective and no increment in calculation of signal processing.

Key words： GPS signal; oppressive jamming; C/N0; I channel; Q channel
