摘要
Outside wireless signals often obstruct GNSS receivers from acquiring satellite signals. Traditional anti-jamming algorithms are used to suppress interference using a convex optimization method based on minimizing output power. These algorithms can reduce interference. However, these models suppress satellite signals as well as jamming interference. Under the high-dynamic condition, the output signal-to-interference-and-noise ratio (SINR) deteriorates seriously and the success rate in acquiring satellite signals falls accordingly. This paper introduces a novel, broadened model with a no-main-lobe-and-multi-virtual-null-constraints (NMLCB) method based on maximizing output power and constraining interference sources. With the new method, GNSS receivers can receive satellite signals more easily than using the power inversion (PI) and power minimization with derivative constraints null (NB) methods under the high-dynamic condition.
