Too Long; Didn't Read
The pipeline of anomaly detection and false alarm elimination is shown in Fig. 1. The algorithm assumes no anomaly if the estimate is within the normal speed range. The flow speed estimate is checked against the glider-estimated flow speed to circumvent any false alarm. This paper is available on arxiv(https://arxiv.org/pdf/2308.00180.pdf) under CC 4.0 license.

II. ANOMALY DETECTION ALGORITHM
The pipeline of anomaly detection and false alarm elimination is shown in Fig. 1. By generating the glider speed estimate, the algorithm assumes no anomaly if the estimate is within the normal speed range. Otherwise, the glider may be encountering issues. The flow speed estimate is checked against the glider-estimated flow speed to circumvent any false alarm.
We model the glider dynamics as follows:
where θ is the unknown parameter to be estimated,
