Abstract: Highlights•This paper develops a ranking-based filter pruning technique for effective model compression.•We further incorporate an effective channel attention module to capture more discriminative features.•We introduce a classification ranking loss and IoU-guided ranking loss to facilitate the consistent optimization of classification and localization.•The proposed RB-SiamCAR model outperforms other trackers, showing its superiority in UAV tracking scenarios.
