ABSTRACT
Antenna arrays, which equipped with space-time adaptive processor (STAP), could suppress interference effectively in global navigation satellite system (GNSS) receivers. However, they also break the structure of navigation signal, which may introduce significant measurement biases into the receivers. In this letter, we analyze the fundamental reason of introducing measurement biases, and we propose a STAP structure which can preserve the integrity of navigation signal. The delay of the proposed STAP structure is zero in GNSS receivers, which is demonstrated by theory analysis and simulation experiment.
