Discriminability-Driven Spatial-Channel Selection with Gradient Norm for Drone Signal OOD Detection
Chuhan Feng, Jing Li, Jie Li +2
We propose a drone signal out-of-distribution (OOD) detection algorithm based on discriminability-driven spatial-channel selection with a gradient norm. Time-frequency image featur…
Cognitive Fusion of ZC Sequences and Time-Frequency Images for Out-of-Distribution Detection of Drone Signals
Jie Li, Jing Li, Lu Lv +2
We propose a drone signal out-of-distribution detection (OODD) algorithm based on the cognitive fusion of Zadoff-Chu (ZC) sequences and time-frequency images (TFI). ZC sequences ar…
Dim and Small Target Detection for Drone Broadcast Frames Based on Time-Frequency Analysis
Jie Li, Jing Li, Zhanyu Ju +2
We propose a dim and small target detection algorithm for drone broadcast frames based on the time-frequency analysis of communication protocol. Specifically, by analyzing modulati…
Drone Remote Identification Based on Zadoff-Chu Sequences and Time-Frequency Images
Jie Li, Jing Li, Lu Lv +2
We propose an algorithm based on Zadoff-Chu (ZC) sequences and time-frequency images (TFI) to achieve drone remote identification (RID). Specifically, by analyzing the modulation p…
