Abstract:
This paper introduces a coherent 2x2 SoftwareDefined Radio (SDR) based antenna array designed to mitigate interference within the Global Navigation Satellite System (GNSS). It first proposes an innovative method for estimating satellite steering vectors. The study integrates Minimum Variance Distortionless Response (MVDR) and Linearly Constrained Minimum Variance (LCMV) techniques into a GNSS receiver’s tracking system to counteract interference. Results demonstrate the significant enhancement in tracking loop resilience, preventing lock loss in the presence of highpower chirp jamming signals, thus advancing receiver performance under challenging signal conditions.
